the maize weevil ( sitophilus zeamais ) , known in the united states as the greater rice weevil , is a species of beetle in the family curculionidae .

it can be found in numerous tropical areas around the world , and in the united states , and is a major pest of maize .

this species attacks both standing crops and stored cereal products , including wheat , rice , sorghum , oats , barley , rye , buckwheat , peas , and cottonseed .

the maize weevil also infests other types of stored , processed cereal products such as pasta , cassava , and various coarse , milled grains .

it has even been known to attack fruit while in storage , such as apples .

also known as the greater rice weevil . maize weevils are frequently regarded as primary pests of grain since they are able to infest otherwise undamaged grain .
“the maize weevil’s entire life cycle is centered on one kernel of corn , ” said michael toews , the uga entomologist working to control the pest .
detection methods because the maize weevil larvae develop inside the grain it is difficult to detect the pest by visual inspection unless its numbers are very high .
it is possible to confuse the maize weevil with other storage insect pests such as the larger grain borer – lgb ( prostephanus truncatus ) . the end of the body of the maize weevil is more rounded than that of the lgb , and its mouthparts are ' beak - like ' and antennae elbowed .

maize weevil , sitophilus zeamais motschulsky , is a cosmopolitan pest of stored products ( longstaff 1981 ) , and prior to the introduction of the larger grain borer , prostephanus truncatus , it was reported as the most important pest on stored maize in africa . sitophilus zeamais is the dominant species on maize
biological pest control there have been various studies on biological control agents for the maize weevil . various parasitoids ( anisopteromalus calandrae , cephalonomia tarsalis , lariophagus distinguendus and theocolax elegans ) could be effective if introduced early in the storage period . the fungus beauveria bassiana can be used as a biological insecticide to control maize weevil in stored maize . the bacterium bacillus thuringiensis can be used on adults .
this weevil is a cosmopolitan pest of grain , preferring whole grain to flour or meal .

uga grains agronomist dewey lee said maize weevils have been a big problem for corn growers . lee suggests that growers look for maize weevils around the edges of the field first .
the maize weevil ( sitophilus zeamais ) can be separated from the granary weevil ( s . granarius ) by the presence of wings beneath the elytra ( absent in s . granarius ) and by having circular , rather than oval , punctures on the prothorax . the larvae of the two species are not easy to separate .
adults are reddish brown beetles with a characteristic long weevil snout and have 4 yellow to red spots on the elytra .

the greater rice weevil is a pest of stored product . they are small brown black weevils with a long slender snout and four reddish brown spots on the wing covers ( two spots on each wing cover ) . the head and thorax are nearly as long as the wing covers . it is similar to the rice weevil ( sitophilus oryzae ) but slightly larger with more clearly marked red - brown spots on the wing covers . the greater rice weevil is a stronger flier than the rice weevil
adults are identical in external appearance to the rice weevil ( sitophilus oryzae ) ; dissection required to distinguish between the species .
and since maize weevils can grow from egg to egg laying adult in less than one month , they can be a formidable foe in and around the home . if you suspect you have maize weevil activity , there are several things you must do to knock out current activity and insure new populations won’t quickly emerge .

weevil - damaged grain can be readily recognised by the presence of large holes which are the exit holes of the emerging adults .
the weevil infests the corn in the field and continues to develop after the corn is placed in the grain bin for storage .
the greater rice weevil is a serious pest of stored grain and seeds . they are a primary pest of grain as they can infest undamaged grain . they feed on grain , maize , rice , peas , cottonseed and other stored products . in america , they are a major pest of corn and known as maize weevils .

the female lays an average of 10 eggs on a grain of maize and the hatched larvae bore into the grain .
sitophilus zeamais is a key pest of stored maize causing serious economic damage . the predominant control of this pest is the use of synthetic residual pesticides , which have adverse effects on consumers and environment . the use of phytochemicals for controlling storage pests constitutes an attractive alternative to synthetic products , since plant may be more biodegradable and safer . the aim of this study was to evaluate the activity of neempro ® against the maize weevil on three maize varieties in the laboratory and the effect of the insecticide on seed germination .

the adult rice weevil is 2 . 5 - 3 . 5 mm long and has a slender , hard - shelled bodies that appear pitted or scarred with tiny holes .
maize weevil populations build up the longer the maize is kept in store so it is important to inspect the stock regularly . if the pest is found then some form of treatment will be required . synthetic pyrethroid insecticides such as permethrin and deltamethrin are not very effective against maize weevils which are more susceptible to organophosphorus insecticides such as fenitrothion and pirimiphos - methyl . fumigation with phosphine or methyl bromide is very effective in large - scale stores . also grain stocks may be fumigated with phosphine . pesticides are poisons so it is essential to follow all safety precautions on labels .

investigations concerning the influence of four weevil densities , three oviposition / feeding periods , two maize genotypes ( susceptible and resistant ) , and three kernel densities on the aggregation of maize weevil ( mw ) , sitophilus zeamais motschulsky , eggs indicated that each had a significant impact on egg distribution . results showed that egg aggregation generally increased with increasing mw density and duration of oviposition / feeding period , but the specific response depended on kernel density and maize genotype . these findings serve to illustrate the influence of four environmental factors on the biology and ecology of the mw , as quantified by changes in egg distribution , and may aid in the identification of factors ( such as resistant varieties ) that can be manipulated to the detriment of the insect pest in a pest management program on stored grains .
the adult granary weevil is a somewhat cylindrical beetle about two - tenths of an inch ( two to three mm ) long . the head is prolonged with a distinct snout extending downward from the head for a distance of about one - fourth the length of the body . the weevil is polished red brown to black with ridged wing - covers and a well - marked thorax with oval pits . unlike the rice and maize weevils , the granery weevil cannot fly . the egg hatches in a few days into a soft , white , legless , fleshy grub which feeds on the interior of the grain kernel . the grub changes to a naked white pupa and later emerges as an adult beetle .

4 ) now that you’ve treated all cabinets , pantries , rooms and baseboards where adults may be hiding , install some of our maize weevil pheromone traps where you have or suspect activity . these traps use strong pheromones and sex attractants to lure adults . once they crawl or fly into the holding tray , the thick catching oil will hold them for good .
in stored maize , heavy infestations of these pests may cause weight losses of as much as 30 - 40 % , although losses are commonly 4 - 5 % . s . zeamais has been found to be amongst the most important pests of maize in a number of studies ; in south carolina , usa , (

as the name implies , they like maize . however , maize weevils can be found eating just about anything in the home . more common food stuff they like include seeds of all types , dried beans , cotton , nuts , cereal , any wheat product , corn , flour , pasta , bread and other grain products found in any home .
pupation takes about 1 week at which time adults will emerge . maize weevils present more of a nuisance than other pantry pests because adults feed just as much as their larva preferring a wider range of things to eat . since they fly well and are small , maize weevils can move throughout the home easily finding all kinds of things to eat .

now if you’ve been seeing maize weevils foraging on kitchen counter tops or the floor , the xlure trap will be better suited for these “out in the open” placements . the xlure trap has a protective , hard plastic body to the trap and the catching gel , bait and pheromone is located safely inside out of sight . maize weevils will readily find their way inside and get caught but because of it’s design , the xlure traps are best suited for trap placements that need to be done out in the open .

the rice weevil is a small snout beetle which varies in size , but it averages about three thirty - seconds inch in length . it varies from a dull red - brown to black , and is usually marked on the back with four light red to yellow spots . the rice weevil has fully developed wings beneath its wing covers and can fly readily . the thorax is densely pitted with somewhat irregularly shaped punctures , except for a smooth narrow strip extending down the middle of the back . the larval stage of this insect is a soft , white , legless , fleshy grub which feeds on the interior of the grain kernel . when mature , the grub changes to a naked white pupa and later emerges as an adult beetle .

maize weevils were reared on whole clean , undamaged and disinfested maize grains shaba , the composite mostly grown by adamawa farmers under ambient laboratory conditions . adult weevils were obtained from a colony kept since 2005 in the laboratory of entomology at the university of ngaoundere . maize grains were sterilised in cold chamber at −14 °c for 21 days to kill any incipient infestation . the sterilised grains were conditioned during 14 days prior to rearing or bioassay processes . twenty adults were released into ten glass jars ( 900 ml capacity ) containing 500 g of conditioned grains each . the adults were removed after 2 weeks and the grains were kept under ambient laboratory conditions [ temperature ( t ) = 21 . 9–24 . 4 °c and relative humidity ( rh ) = 75 . 3–78 % ] for the development of progenies . adults aged 7–14 days and mixed sexes were used for all bioassays .
maize weevils lay eggs with a glue like excretion which helps to attach them to surfaces where food is likely to be available . this helps to keep them in place so that just “wiping” a damp rag over the area is never enough ; vacuuming will no doubt help to remove more .
apply it with one of our pump sprayers which will allow you to get good coverage quickly . focus in on baseboards , moldings and floor joists if accessible . since rodenticide is one of their favorite foods , be sure to check any bait placements you have done in the last couple of years . attics are common areas where maize weevils thrive and then find their way inside living areas . if you have an attic with rodenticide , be sure to remove any suspected of feeding maize weevils and treat with defense to insure migrating adults won’t be able to find their way inside .
prior to filling the bins , it is essential that growers thoroughly clean out any old grain and clear vegetation around the outside of the bin where insects could be , he said . maize weevils are strong fliers and can easily move from spilled grain and residues into the newly harvested crop .

estimated the toxicity of deltamethrin to a number of resistant and susceptible populations of s . zeamais in traditional maize stores in togo . in another study , a treatment with pirimiphos - methyl and deltamethrin was most effective in traditional granaries after pirimiphos - methyl , deltamethrin and permethrin were applied in various combinations (
the female weevil chews a hole in the grain and deposits a small oval white egg inside . the egg hatches into a white legless grub which feeds inside the grain . the larvae pupate inside the grain and emerge as adult beetles by biting a circular exit hole through the grain . a female can lay 300 - 400 eggs in her life time . adults live for five to eight months .
if you are not sure if something has activity , store it in a plastic bag and check it every day to two . if there are any maize weevils in the food , they will try to get out within a week or two . if some are found , throw away the entire bag immediately .
to control the pest , toews is evaluating grain protectants — insecticides that are applied at very low rates ( as low as 1 part per million ) to prevent maize weevils from eating stored corn . “we are looking at different chemistries to find solutions that are most appropriate for south georgia and alabama conditions , ” he said .

both s . oryzae and s . zeamais are able to develop on a wide range of cereals and also on processed cereal products such as pasta . however , food preferences of the two species are variable ; it is clear that s . zeamais is predominantly found associated with maize grain , whereas s . oryzae is associated with wheat .

the egg incubation period of five days observed among food hosts was similar to what was obtained in other related coleopterans , three to four days for s . rugicollis [ 21 ] and five days for s . oryzae when it was cultured on maize grains [ 22 ] , whereas it was three days for s . linearis cultured on tamarind [ 17 ] and four days for conotrachelus psidii [ 23 ] . there was variation in mean egg laid by mated female s . zeamais in relation to food hosts ( range between 54 and 67 eggs ) with more eggs laid on maize over a period of almost 22 days . s . zeamais could live for 117 to 126 days on cereals , with longest duration occurring on millet , maize , rice , and sorghum in that order . this variation could be a result of food hosts used and prevailing environmental conditions . the developmental biology of s . zeamais could be influenced by this moderate fecundity and oviposition , shorter larval period , and ability to breed easily on any cereal crop .
maize weevils start their life as a small caterpillar like larva which hatches on some type of food like a wheat grain , seed or nut . eggs will hatch within a couple of days of being laid and feed immediately . feeding will occur for 1 - 3 weeks and then larva will spin a cocoon in which they will pupate to an adult .

maize weevils are small , fast and quick to hide when ever people are around disturbing where they have been feeding . many will go unnoticed and missed so it is best to treat every cabinet to be sure you get proper coverage . let the treatment dry for 1 hour and all dishes and food stuff can then go back away without hazard to people or pets .
good store hygiene plays an important role in limiting infestation by s . oryzae and s . zeamais . the removal of infested residues from last season ' s harvest is essential . the use of resistant maize varieties has also shown some potential in slowing the build - up of insect densities in stores . phenolic compounds have been associated with grain resistance to s . zeamais .

the study shows that neempro ® is very effective against s . zeamais on the grains of three maize varieties ( clh103 , cms8501 and shaba ) . this insecticide , not only kills the adult weevils , but also affects their progeny production . additionally , it protects stored grains of the three varieties for 4 months without affecting the seed germination power . however , the product seems to have protected clh103 and cms8501 varieties more than shaba . therefore , neempro ® can be used as post - harvest grain protectant against the infestation of the noxious s . zeamais . with this in mind , further research is needed in the future to investigate the effect of this botanical insecticide on other stored products pests and to determine the biochemical parameters of the three maize varieties .
the only way to control these pests is fumigation . since it is an internal pest , residual control will only kill exposed adults . to kill the internal stages ( larval and pupal ) , you must fumigate . heating grain to 60c can kill larvae , however , this may decrease germination and baking quality of flour . “if you dry corn in the field , the corn will become infested with maize weevils , ” says extension agricultural engineer paul sumner . “once a weevil feeds on an ear of corn it ' ll emit a pheromone which will attract other maize weevils to that area . they subsequently lay eggs in the mature kernels , and adult weevils emerge within 2 - 3 weeks . ” by delaying harvest in the field , growers allow a second infestation of weevils in the corn , says sumner . “it ' s going to occur anyway in our part of the country . do you leave corn in the field and let it dry , or do you harvest it after it has field dried ? then , do you store it or sell it immediately ? ” if you plan on storing corn , then you ' ll have to place some insecticide on it to prevent a regular occurring infestation of weevils inside the storage bin , he says .
s . oryzae and s . zeamais are very important pests of cereals . in maize or sorghum , attack may start in the mature crop when the moisture content of the grain has fallen to 18 - 20 % . subsequent infestations in store result from the transfer of infested grain into store or from the pest flying into storage facilities , probably attracted by the odour of the stored grain .

if a female meller’s chameleon has indicated she is receptive to the male’s advances , they may mate several times over a period of days . females can store sperm from a mating for several months , enabling them to lay several clutches of eggs during the year from a single encounter . most clutches have between 50 and 90 eggs . the female buries the eggs in a hole in the ground , covers them and leaves . after four or five months the young meller’s chameleons hatch from their eggs to fend for themselves . adult meller’s chameleons neither guide nor protect the hatchlings .
avoiding veterinary care and medical treatment may cost the chameleon it ' s life , which will certainly cost the owner their original investment in purchasing the chameleon . here are some suggestions for safeguarding the health and longevity of a newly imported chameleon :
the largest chameleon is the parson’s chameleon , according to encyclopedia britannica . it can grow up to 27 inches ( 69 . 5 centimeters ) long . the madagascan , also known as the oustalet ' s chameleon , is also very large and grows up to 23 inches ( 60 cm ) long .
meller ' s distinguish themselves from their universally bizarre - looking cousins with a single small horn protruding from the front of their snouts . this and their size earn them the common name
giant one - horned chameleon .
most chameleons have casques or crests on their heads , the size and shape of which varies by species . the meller’s chameleon has a pair of “occipital lobes , ” or ear flaps , that can flare up like an elephant’s ears . they raise these flaps during courtship and threat displays .
meller ' s chameleons are also called

the island of madagascar is home to around 50 percent of the world’s chameleons . one hundred fifty species of chameleon inhabit the island , which has a diverse range of habitats , including desert and rainforest . most of the island’s chameleons are forest floor dwellers , as opposed to arboreal . since the chameleon is incapable of flight , madagascar’s native chameleons are physically isolated from the rest of the world’s chameleon population . this means that they have evolved independently from other species .
while adult meller’s chameleons ( chamaeleo melleri ) are beautiful , they are more difficult to maintain than some of the other species of chameleons that are more hardy and easier to keep .
meller’s chameleons should be kept in a quality screened cage like the reptibreeze aluminum - framed one pictured below . please do not keep your chameleon in a glass - sided cage , as they do not provide enough ventilation , which can lead to respiratory issues .
other types of chameleon will usually not decline if not provided with proper humidity and fresh water continually for a few days ( not that this is ever recommended ) , but it doesn’t take long for a meller’s to go downhill if the owner doesn’t stay on top of this all the time . this is probably the main reason why your herper friends tried to dissuade you from purchasing a meller’s . i’m glad you listened , as there are many other types of chameleon that don’t have such specific and difficult to maintain requirements .

: because meller’s newborns are big , relative to other chameleon species , they progress to eating large prey quickly . hatchlings begin with small insects , flies , bugs , and worms . as adults they consume locusts , cockroaches , spiders , small lizards , and hatchling birds : anything that moves and is the right size . this lizard is also known as “the bird eating chameleon” . they are carnivorous .
oustalet’s start at about 3 inches long but can reach 27 inches or larger .
crickets and dubia roaches are the most commonly available prey items that are appropriate for meller’s chameleons , and most keepers will feed these . the insects should be gut loaded , meaning they should be fed healthy greens , fruits and grains prior to being offered to your chameleon , so those nutrients can be passed on to your pet .
the indian chameleon ( chamaeleo zeylanicus ) , despite its name , lives in sri lanka , parts of southern asia and india . it is typical of most lizards , in that it prefers to live in trees , rather than on the forest floor . europe’s only chameleon is the mediterranean chameleon ( chamaeleo chamaeleon ) . he lives in greece , spain , malta and italy .
the dead chameleon pictured above was one of several dead animals observed at exporters ' holding facilities .
as with all chameleons , meller ' s will change colors in response to stress and to communicate with other chameleons . their normal appearance is deep green with yellow stripes and random black spots . females are slightly smaller , but are otherwise indistinguishable from males .
observation is critical in the daily assessment of the health of wild - caught chameleons , but keep physical handling and traffic in the chameleon ' s visual range to a minimum . provide ample drinking water and ensure the chameleon is drinking . keep records of food and water consumption on a daily basis .
exotic pet enthusiasts often attempt to keep meller ' s chameleons as pets . however , they are highly susceptible to even the slightest level of stress and are very difficult to care for in captivity . in the wild , they can live as long as 12 years .
stress is always a concern . a wild - caught meller’s chameleon is already dealing with the stress of capture and importation , and continued stress will impair its immune system and lead to illness and death . many things can cause stress , including improper temperatures and lighting , inadequate housing , being able to see people or other animals , and being handled or bothered too frequently .
other chameleon species lay eggs that have an incubation period of four to 24 months , depending on species , according to the san diego zoo . the size of the chameleon predicts how many eggs she will lay . small chameleon species lay two to four eggs while larger chameleons lay 80 to 100 eggs at one time .
the adult size of the meller’s chameleon is approximately 28 inches in length , and because of their extremely large size , they require a very large habitat or perhaps an entire room . their potz is 77 to 80 degrees fahrenheit , which should be easy for a herper to provide . the biggest problem with maintaining these chameleons is that they require an ambient humidity of 95 to 100 percent , which is almost impossible to maintain without humidifiers , misters and specialized enclosures to hold the humidity . meller’s chameleons also require a constant source of fresh water from a drip system or mister and will quickly fail to thrive unless kept well hydrated on a daily basis .
: meller’s chameleon has adapted to a very specific environmental niche and cannot respond to change or move away quickly . human activity is encroaching upon its habitat , altering and degrading it . because of its large size and handsome appearance , although it is illegal to do so , the pet trade seeks out this species . however , it is extremely susceptible to stress and many do not survive being transported .
the smallest chameleon has a special distinction . it is also one of the smallest vertebrates ever discovered . the leaf chameleon grows to just 0 . 5 inches ( 16 millimeters ) and can sit comfortably on the head of a match .
she named
nosey
. this chameleon had been rescued from being euthanized in a pet store due to declining health by bianca and her friend mary ellen mcloughlin , a veterinarian . nosey ' s initial health problems were serious :
when first getting a chameleon try not to handle it too much when it is young . as it gets older , be very patient and cautious when your chameleon starts getting used to you . chameleons are very trust - oriented , so if you grab them off their branch or make surprising sudden movements while handling your chameleon you may lose his or her trust .
water is very important to chameleon growth and health . they either slurp water up using their tongues or the inhale it .
guarantee that someone very experienced with reptiles will attempt to select the specific lizard ( s ) you are requesting .
changing skin color is an important part of communication among chameleons . according to the san diego zoo , a chameleon ' s skin changes colors in response to its emotions , such as anger or fear , changes in light , temperature or humidity .
meller’s are large chameleons that can eat a great deal , and it is important to provide them with a healthy and varied diet . in the wild , they consume a variety of insects , including grasshoppers , flies , moths and beetles . some have even been known to consume small lizards and birds . you can feed pet meller’s crickets , dubia roaches , silkworms , and praying mantises , to name just a few options . these large chameleons will also enjoy larger prey items and flying insects , too—favorites of mine include mantids , dragonflies and butterflies . of course , care must be taken to ensure any prey items are not toxic and have not been in contact with pesticides .
2 . colour changing . most chameleons change from brown to green and back , but some can turn almost any colour . a change can occur in as little as 20 seconds . chameleons are born with special cells that have a colour or pigment in them . these cells lie in layers under the chameleon’s outer skin . they are called chromatophores . the top layers of chromatophores have red or yellow pigment . the lower layers have blue or white pigment . when these pigment cells change , the chameleon’s skin colour changes .
additionally , until the gender of your meller ' s is confirmed i would recommend having a laying bin available just in case , especially with fresh wc females who may be coming into the country gravid . i use a large plastic storage tote ( like in the photo above ) filled more than 12
deep with organic topsoil mixed with sand .
water is the most critical element to keeping meller’s chameleons successfully , whether your chameleons are fresh imports or long - term captives . they should be provided with at least three 20 - minute misting sessions daily , but i provide an even longer one in the morning of about 45 minutes , as this seems to be when my chameleons drink the most .
wild - caught imported chameleons usually carry a much lower price tag than captive - raised chameleons . however , if the imported chameleon you purchase requires several courses of treatment for medical problems , the veterinarian costs may well run two to three times the original price of the chameleon .
the buyer , unaware of what may have recently transpired in the life of the brilliantly colored chameleon pacing nervously in the pet store , buys what they may believe to be a healthy animal . as proof of health , sellers routinely assure buyers that a chameleon has been deparasitized and is eating . the new owner takes their chameleon home with high expectations that it will thrive and even reproduce . under the best of conditions , a veterinarian examines the chameleon and minor health problems are treated successfully . unfortunately , even these chameleons may fail to thrive due to maladaptation .
1 . almost half of the world’s chameleon species live on the island of madagascar , with 59 different species existing nowhere outside of the island . there are approximately 160 species of chameleon . they range from africa to southern europe , and across south asia to sri lanka . they have also been introduced into the united states in places such as hawaii , california and florida .

thanks for writing this olimpia , there isn ' t much info about meller ' s chameleons out there . do you free range your mellers , or do you keep them in an enclosure ? what size is your enclosure ( if you use one ) ? have you figured out the sex of your mellers ? i love your blog , thank you for sharing !
jackson’s chameleon in the wild , jackson’s chameleons can be found in east africa . they were also introduced to hawaii where wild specimens can now be found . they can grow to be around 13 inches long and can live up to 8 years . a daytime temperature of 75 to 80 * f and a humidity level around 65 % is required . these three horned chameleons are readily available as pets .
keeping your pet and it ' s environment clean and hygienic is important for it ' s overall health . there are some important cleaning supplies that you should always have on hand and some important factors to pay attention to when it comes to their overall grooming .
meller ' s need uvb and a basking bulb , like other chameleons . i use a reptisun 10 . 0 bulb as my uvb bulb and a 60w halogen spotlight as a heat light . this leaves my basking spot no higher than about 85f while the rest of the enclosure stays at room temperature ( 75f ) . and at night i let the temperature drop as it will , so they can cool off overnight . like all chameleon species , they thrive with a nighttime temperature drop of about 10 degrees or more .
they should not be considered lightly as a pet chameleon . they are very sensitive to stress , are usually wc , and need copious amounts of room , water , and food . so anyone who cannot meet these needs should consider a different or smaller species of chameleon to start off with first .
purchase imported chameleons from reputable sellers who offer a guarantee if you are dissatisfied with the chameleon , it is diagnosed by a veterinarian with serious health problems , or dies . ask the seller how many days you have to make a determination before the guarantee expires . remember that it may take several days to receive the results of some diagnostic tests . understanding the seller ' s guarantee is especially important if you are purchasing a chameleon by mail order .

whether your meller’s chameleon is in a free - range setup or in a large enclosure , uvb light is a must . exposure to uvb from either direct sunlight or a proper uvb light allows the chameleon to properly metabolize calcium in its system to keep its bones strong . there are a variety of quality uvb lights of different strengths available in pet stores and other places that sell reptile supplies . commonly used bulbs include reptisun and reptiglo 5 . 0 bulbs , though in a large and / or heavily planted free - range setup it can be beneficial to use bulbs with a higher uvb output . twelve hours on and 12 hours off is the usual light cycle , though this can be adjusted to mimic seasonal daylight hours .

many t . melleri are wild - caught specimens , meaning they can be difficult to acclimate and which has led to the nickname “the 90 - day chameleon . ”
as a hatchling , a veiled chameleon is approximately 4 inches . although an adult female can grow up to 18 inches , a male may only reach 2 feet .
these are all common questions when it comes to owning and caring for these friendly color changing reptiles . that’s why we put together this comprehensive guide !
i toured three exporter ' s facilities in madagascar in 1996 and 1997 . the conditions varied in each one , and my observations were as follows :
these are 5 - 12 months . you need to feed them on 6 - 10 crickets the size of the gap between their eyes . proper cricket sizes for a juvenile chameleon are at the low end ½ inch , 5 / 8 inch , then ¾ inch a day . if you feed your chameleon crickets that are much too large such as adult crickets , your chameleon may choke . since overfeeding can lead to the development of mbd , as the chameleon grows older you need to keep an eye on how much they eat . when offering large quantities of food , it’s very hard to manage your supplementation . by feeding them consistently and with good quantities , you are likely to help them develop strong , dense bones that can support them well . you can only do this if you regulate the quantity of food .
in 2008 i bought my first chameleon . nine years later , i still can’t stop talking about them and helping people become confident , capable chameleon owners . i ' m olimpia martinotti - follow along to learn about the care , breeding , and rehabilitation of chameleons in captivity through a biologist with almost two decades of exotic animal experience .
carpet chameleon the carpet chameleon is found in madagascar . they are a smaller species and males grow to around 9 inches long . they have a short lifespan and only live for 2 to 3 years . daytime temperatures should be around 75 * f with 65 % humidity . they are active and hardy chameleons that do well as pets .
if you want your pet to stay healthy and enjoy a long life , it’s very important to provide them with appropriate lighting . this not only makes them a lot more comfortable , but is necessary for their survival , since they don’t produce heat internally . lighting supplies that you need to have for your chameleon include :
we accept visa , mastercard , american express , discover , and paypal . we do not accept checks , money orders , or cashier ' s checks .
people who don’t have the space to provide a free - range situation , or who have cats , dogs or housemates that would make free ranging impossible , may need to provide a cage for their chameleons . i always suggest they buy or build the largest cage they can . it will likely have to be custom built , as there really aren’t any suitable ones on the market that i think would make proper enclosures for meller’s chameleons as is .
despite this loss , our love of t . melleri did not die . i did more research , learned about the benefits of free - range setups , and set out to create such an environment . once it was ready , we brought home another pair of meller’s chameleons , and a few months later , we got a couple more . we continued adding to our colony , and eventually we had a group of 14 beautiful t . melleri .
i feed each of mine a different amount of food daily . but fewer items is usually better with most chameleons , as we don ' t want them to get overweight . since most meller ' s available are adults , the amount you feed them ( usually every other day or every two days ) will depend on what they need to maintain a healthy weight . typically a small handful of feeder items every other day or every two days .
when basking , the side facing the sun will turn dark green to almost solid black . the shaded side will stay the individual ' s normal resting color .
whether you would like a female chameleon as part of a breeding project , as a pet , or both , how you take care of them will vary a litt . . .
while it does not occur in every case , the next stage seems to determine whether or not the chameleon survives . food intake often ceases and the chameleon appears depressed or nervous , and may pace the perimeter of the cage . it is at this crossroad where the chameleon either seems to accept captivity and continues life , or begins a downward spiral to death . i believe this to be the essence of maladaptation . those chameleons that simply cannot tolerate their loss of freedom coupled with human interaction , or whose health has been irreparably damaged by the rigors of being transferred into captivity simply waste away . probably the single most critical factor in maladaptation is the level of prolonged stress the chameleon has endured from the point of capture .
there is little information on this species , and nothing is known of population trends . it is widespread , but because it is a large bodied chameleon , it is probably not locally abundant .
four - horned chameleon the four - horned chameleon can be found naturally in cameroon . they live for around 5 years and can grow to be 14 inches long . they require daytime temperatures around 75 * f and a relative humidity of at least 85 % . they are attractive chameleons that tend to do well in captivity if you can provide a suitable habitat with very high humidity .
there is visible weight loss , sunken eyes , swollen eye ( s ) , general weakness , inability to perch , or eyes are closed ( sleeping ) during daylight hours .
veiled chameleon in the wild , veiled chameleons are found in yemen and saudi arabia . males can grow to be 24 inches long and they can live up to 5 years . they need daytime cage temperatures around 80 * f and a relative humidity of 70 % . veiled chameleons will eat some plant matter in addition to insects . they are popular pets and can make a good first chameleon .
a couple weeks later , it happened again , and the next three months became a nightmare . even with vet visits , tests , and various medications , our chameleons kept dying . eventually , we lost them all . after this tragedy , we didn’t know if we should try again . we were scared , but our love of t . melleri won out . we eventually brought home another pair and , slowly , we added a few more . we now have five healthy , well - acclimated meller’s chameleons .
if you will only be away for a day , your pet will not be without regular misting and food since it may be on an every other day feeding schedule . however , if you will be gone for several days or if you are keeping a baby , you need someone to come and feed your pet . this person needs to be trustworthy and not afraid of insects ! when you are going out of town , the more automated your system the better . it’s also very important to educate your secondary caretaker well about your specific chameleon ' s personality .
5 . ballistic tongues that are 1 . 5 - 2 times the length of their body . chameleons feed by ballistically projecting their long tongue from their mouth to capture prey located some distance away . while the chameleon’s tongue is typically thought to be 1 . 5 to 2 times the length of their body ( their length excluding the tail ) , it has been recently discovered that smaller chameleons have proportionately larger tongue apparatuses than their larger counterparts . tongue projection occurs at extremely high performance , reaching the prey in as little as 0 . 07 seconds , having been launched at accelerations exceeding 41 g . the chameleon tongue’s tip is a bulbous ball of muscle , and as it hits its prey it rapidly forms a small suction cup . [ source 1 , source 2 ]
they are fairly common in the savanna of east africa , including malawi , northern mozambique , and tanzania . almost one - half of the world’s chameleons live on the island of madagascar .
a number of other species ( k . matschiei , k . multituberculata , k . tavetana , k . uluguruensis , and k . vosseleri ) have been mistakenly called by this species ' name or classified as subspecies . in 2008 , it was shown that they actually are their own distinct , different species . the true fischer ' s chameleon is rare with a more restricted distribution than previously believed .
stress coloration : excitement or mild stress begins to show with dark green spotting overlaying the chameleon ' s normal coloration , as above . dark green spots turn to black . as stress builds , the spotting expands to black mottling in all stripes . low - level stress , such as a mild parasitic infection , left unalleviated over long periods , will turn the chameleon brown , pink , gray , and white mottled . as stress becomes severe , the chameleon starts to turn charcoal gray , eventually turning pure white with yellow stripes . at this point , the animal is near death from extreme stress . never buy a melleri that is gray or white . a gravid melleri is cream , gray , and black colored , with a bloated torso , and should be considered
at risk
, not a good candidate for purchase .
females are usually ready to mate when they are 1 year old . the first sign that a female chameleon is ready for breeding is her color . she will have begin to take on a dull orange hue .
when these criteria are met , you can perch a male chameleon on your hand and move it towards the female . if the female is ready you will witness a complete change of demeanor . the male chameleon will then head - bob while moving towards the female . once copulation starts , breeding can go on for several hours . you might keep them together for up to two days until the female starts rejecting the male .
your pet ' s main method of communication is through color change . this can indicate good health , stress or even reproductive condition . understanding this can greatly assist you when caring for them .
no matter what species , chameleons become mature at 1 to 2 years of age . the exception is the madagascan chameleon . it has been labeled as the vertebrate with the world ' s shortest life span , according to encyclopedia britannica . their eggs hatch in november , the young become adults in january , they lay eggs in february , and then the entire adult population perishes after a lifespan of just three months .
although it’s recommended to have live plants , if you cannot , fake plants will do the trick . live plants will not only provide better cover but will also provide good surfaces for drinking water . make sure to have enough foliage to provide a basking spot , but also have a lower portion of the cage that is shaded and much cooler . this will allow your chameleon to escape the heat and remain comfortable .
while living in the wild , chameleons have a lot to worry about . this includes getting attacked , eaten , and not getting enough of their daily necessities . that ' s why it ' s your job to ensure that your pet doesn ' t have to deal with any of these issues in your home . when chameleons are in bad shape or look hurt it often means they are suffering from psychological stress .
chameleons are different from many reptiles because some of the species , like the jackson’s chameleon , have live births . these species can give birth to eight to 30 young at one time after a gestation of four to six months . while the young are born live instead of in an egg , they started as an egg . these mothers incubate the eggs , minus a shell , inside of her body instead of laying them in a nest .
chameleons are very sensitive animals that need specialized care . without proper care , your pet chameleon can quickly become ill . the most important thing for your designated caretaker to know is what can make it ill and how to keep it comfortable .
with all but one inch of his tail amputated . this animal ' s tail had been run over by a passing car , according to a man who lived in the area where i found this chameleon . it appeared to have healed without incidence as the wound was quite old , and he was in otherwise robust condition . i also encountered two chameleons with wounds near the mouth , one of which was badly infected ; however both appeared to be in otherwise good condition .
we now had two free - range setups : one that was used as a quarantine area for new arrivals , and an expanded , room - sized living area for our existing chameleons . we even had a free - range nursery area for a couple small juveniles that we acquired . over the next couple years , we watched our gentle giants blossom . they were a friendly and inquisitive group . they welcomed visitors , as they knew we would offer them treats to show their long tongues in action . a couple of our meller’s were even calm to the point that we could bring them to educational events where we introduced the public to chameleons .
if your chameleon experiences a minor wound , keep it clean and treat it with a topical agent such as silvadene cream or my favorite , vetericyn hydrogel , which is an excellent all - purpose ointment for wounds . of course , severe injuries and infections should be looked at by a veterinarian to determine a course of treatment . parasites are the biggest concern , as a heavy parasite load can lead to decreased appetite , increased dehydration and , eventually , death . a fecal examination should be done to determine the specific parasites and the level of infestation . i prefer to wait until the chameleon is stabilized before treating parasites to avoid further stress caused by administering the medication and the effect the medication may have on an already stressed animal’s system .

this can be any bulb that generates heat . since chameleons are cold blooded , they must absorb heat from their environment to regulate their body temperature . in order to digest their food well , they need a warm place to bask . basking bulbs will provide them with warmer temperatures but should not produce so much heat that your pet ' s health is interfered with . depending on your reptile ' s metabolic needs , it will utilize different temperatures throughout the day
there are many different ways to set up a free - range environment for meller’s chameleons , whether you have an entire room available or just part of a room . i use wire shelving units that are available at home improvement stores . i remove any middle shelves , leaving just a top and bottom shelf . trees ( ficus , for instance ) and other sturdy plants for the chameleons to climb upon can be placed on the bottom shelf and lights can be either on the top shelf or suspended from the ceiling above the unit . the misting nozzles can be attached to the top shelf as well , with pans positioned below to catch the water .
different species all have different standard temperaments . this is further compounded by the fact that each individual reptile will have it ' s own personality as well ! fortunately , there are some basic guidelines to follow to help keep your pet comfortable .
when it comes to keeping a chameleon as a pet , hydration is very important . it’s actually the primary factor that causes deaths when chameleons are in captivity . as compared to other pets , hydrating chameleons is rather involving . for instance , most can not take water from stagnant points . this means putting a bowl of water inside the cage is not sufficient to keep your pet hydrated . chameleons , whether pets or wild , drink water that falls from branches or leaves . this is why getting your pet chameleon to drink water is a hard task . some of these pets may slow down their daily misting consumption and this can leave them dehydrated . this can be hard to understand especially if you are misting the enclosure 3 times a day . some common hydration requirements and supplies include :
although you can feed them up to 12 crickets per day , avoid over - feeding your chameleon . some of these guys are very gluttonous and will keep eating until they are over weight and unhealthy . find out how many crickets your chameleon will eat in one sitting . use that number to either feed half that in the morning and half in the afternoon , or all in the morning . most babies between 2 - 4 months eat about 10 - 15 small crickets daily , though some can eat up to 30 . chameleons are very adaptable to their environment , so if you do not feed your pet enough when he or she is young , it will have a stunted growth . on the other hand , if you over - feed your chameleon it will mature too quickly and likely have health problems as it gets older .
giving this supplement depends on the pet’s exposure to light . if you expose it regularly , then giving the supplement is not important . however , if kept indoors then vitamin d3 is necessary . however , this should only be done once per week .
when it comes to indoor chameleons , this is one of the most important forms of lighting . although uvb cannot be seen it’s important in the manufacture of vitamin d3 . this enables your pet to absorb calcium . lack of this can lead to severe deformation , metabolic bone disease and even death . the uvb bulbs available for purchase usually only last for 6 months before they need to be replaced . you only need to have one bulb for your pet’s habitat . some of the most popular brands are :
when frightened , chameleons will puff up and hiss loudly . they will often change colors into a dark shade of grey / black . handling them too much might also increase their chances of getting sick . in case you have to handle your pet , do not pick it up , but rather place your hand and allow it to climb on it ' s own . also , you should avoid holding its back , neck , tail or feet unless it’s very important to restrain it from hurting itself further .
this is also another method of providing water especially when you have a dehydrated chameleon . just place a large plant at the top and direct the shower towards the wall so that only fine mist reaches the pet . while using this method , ensure that you carry on close supervision .
many people think chameleons change colour to blend in with their surroundings . scientists disagree . their studies show that light , temperature and mood cause chameleons to change colour . sometimes changing colour can make the chameleon more comfortabl . sometimes it helps the animal communicate with other chameleons .

although animals can handle short term stressor , chronic situations can make them sick . if you are keeping a chameleon as a pet , too much stress will not only cause illness but will also make them less social and dampen their spirits . stress can also greatly decrease your chances of breeding them .
this all - inclusive chameleon kit is exactly what we use and contains a zoo med screen cage , reptisun 5 . 0 uvb bulb & lamp , basking bulb & lamp , plastic plant , vine , digital thermometer and hygrometer , hand - pump mister , and calcium supplement , everything you need !
needless to say , meller ' s eat very large prey items ! in the wild they wouldn ' t be above catching small birds , even ! so offering appropriately sized feeder insects is a job in and of itself . i breed a couple species of large roaches on top of the discoid roaches i breed for my other chameleons , in order to have nymphs of a decent size . i also offer hornworms and the manduca moths that they turn into , as these are favorite treats . grasshoppers , katydids , and anything else that is big is going to be a hit with this species . however , mine do still love crickets and superworms so they will still eat smaller items , they just need to eat more of them to compensate for their size .
this means it ' s important to provide your chameleon with a good temperature gradient to allow it to warm and cool itself when it needs to . while the basking spot should be at the top of the enclosure of up to 90 degrees , you should also have the coolest temperature at the bottom . this should come as low as 70 degrees . believe it or not , chameleons can withstand temperatures as low as 50 degrees at night ! while they can handle these low temperatures , they ' re the most comfortable in 60 - 70 degree weather while they sleep .
any animal that can change colours and look in two directions at once is worth learning more about . armed with a tongue you have to see to believe , the chameleon may be one of the coolest reptiles on the planet . here are ten things you may not have known about our lizard friend .
while keeping a chameleon as a pet , avoid handling it as much as possible . chameleons are not only shy animals , they also move very slowly . before reading the rest of this though , keep in mind there are cases of extremely friendly chameleons that do not mind getting touched or picked up .
4 . chameleons vary greatly in size and body structure , with maximum total length varying from 15 millimetres ( 0 . 6 in ) in male brookesia micra ( one of the world’s smallest reptiles ) to 68 . 5 centimetres ( 30 in ) in the male furcifer oustaleti .

like most lizards , chameleons favor a warm habitat . for this reason , the geographical distribution of the chameleon is limited only to regions that enjoy a warm climate . however , this does not mean that all hot regions are natural homes to chameleons . australia , north and south america have no native chameleons .
