the true amano shrimp is caridina multidentata , but you might see them bandied about under their synonym of caridina japonica . certainly when takashi stumbled across and popularised them in the 1980s , that was the name they were recognised by . it was only in 2006 that revision took place and gave them their current identity of c . multidentata .
caridina multidentata is incredibly difficult to breed . though the leaner males will frequently engage with the plumper , larger females , raising the larvae ( sometimes called the zoea ) requires a marine and brackish stage .

caridina multidentata , also commonly known as the amano shrimp , is one of the most effective algae eating animals that can be kept in the freshwater aquarium . they are cherished by keepers of planted aquariums for their industrious behavior and graceful appearance .

they will go up much higher and all the way to 7 . 5ph without problems . above this they don’t fare as well and their lifespans will be shortened . caridina multidentata are pretty resilient when it comes to diseases and aren’t affected by the gamut of usual fish ailments .
caridina multidentata has many names , including amano shrimp , yamato shrimp , japanese swamp shrimp , algae shrimp , and yamato numa - ebi . all of these names refer to the same hard - working algae - eater hailing from the yamato swamps and the island of kyushu in japan , as well as parts of korea and thailand .
being a swamp shrimp , cardinia multidentata is hardy and capable of adapting to various water conditions . it is important to avoid extremes in any water parameters , and to keep those parameters stable .
choose tankmates wisely for this little shrimp . many fish enjoy the taste of shrimp , and any fish with a large enough mouth will likely make a snack out of caridina multidentata . peaceful , smaller tankmates with a similar temperament should be housed with amano shrimp , and plenty of hiding spots should be provided . this is especially necessary when amano shrimp go through the molting process . they are extremely vulnerable during this time , and any stress can be detrimental .

amano shrimp are omnivores and will accept a variety of foods . other than algae , caridina multidentata should be offered suitable vegetable matter such as algae wafers , spirulina , and other vegetables such as zucchini , peas , and seaweed . high quality packaged food intended for invertebrates or bottom feeders works as a good staple or supplement food . live foods such as tubifex / bloodworms and blackworms will be happily accepted . newly hatched brine shrimp , daphnia , microworms , and greenwater are all excellent foods for newly hatched and small algae shrimp .

these ' taimanos ' are identified by two features : the first being their shorter , compact rostrum , and the second being their inherent laziness . supposedly , these false shrimp also breed entirely in freshwater , which is something that c . multidentata do not do . but aside from that they have the same , nondescript colours and similar markings .

amano shrimp tolerate a range of water conditions with the exception of the usual suspects that are ammonia and nitrite . some sources cite caridina as being indifferent to nitrite , but this isn’t always the case . although nitrite reacts in different ways to shrimp blood as it does to fish blood ( contact with the latter forms the lethal methaemoglobin ) , at high doses it can still cause a degree of mortality and difficulty .

the amano shrimp is a very popular shrimp in the hobby . it is second in popularity to the red cherry shrimp . the name amano shrimp originates from the well known aquarist takashi amano who frequently uses the shrimp in his aquariums as algae eaters . however most people do not know that the amano shrimp is a difficult shrimp to breed and that virtually all amano shrimp are caught in the wild and then sold to hobbyists . captive breeding has been achieved but is rare .
as stated above the popularity originated from the aquarist takashi amano . most local fish stores carry this shrimp and even the large pet chains carry it as well . hobbyists sometimes begin with this species to due the ease of acquiring it . the notion that it is a superb algae eater also attracts aquarists who are into planted tanks . unfortunately most of the hobbyists who acquire the amano shrimp do not know that it cannot be bred in freshwater and wonder why the pregnant females with many eggs never produce babies .
as stated before the amano shrimp requires brackish water in order to breed successfully . the pregnant females carry many eggs , most likely due to the loss rate of the larvae after hatching . the shrimp hatches as a tiny larvae free floating in the water . it is not like other shrimp which hatch as miniature adults . the larvae are very delicate and require special care . below is a quick run down on information required to breed this species in captivity . it is a difficult task to captive breed the amano shrimp . however , if you are up for the challenge then good luck . it is definitely an achievement if you are successful !
the adults are kept in a 40 gallon ' breeder ' tank with a sponge filter and lots of hornwort . the ph is close to neutral and the temperature around 75 degrees f . they eat ' gp pellets ' plus the occasional algae tablet - - there ' s also a lot of hair algae in the tank , more than they can keep up with .
larvae are raised in full - strength ( 35 ppt ) seawater that ' s pea - green with tetraselmis algae . no supplemental foods are added . the latest batch was raised in a 2 . 5 - gallon tank - - there was somewhat high mortality , so more space may ' ve been helpful . i ' ve tried a variety of raising conditions . so far , the best results are with : 24 - hour lighting gentle aeration mid - 70 ' s farenheit in those conditions the larvae began metamorphosing into postlarvae after about 20 days . higher temperatures seem to slow development . it took just about 6 months for a full life - cycle from hatching to egg production .
this page will give a completely detailed profile of the selected fish , from a to z . the profiled fish will be chosen randomly by badman , and will come from the complete genre of tropical fish . new profiles are added on a regular basis . if you would like to submit a profile for the site please contact me . don ' t forget to let us know you experiences with this fish by filling out the
considered one of the best algae eating additions for any aquarium . they are highly sought after by hobbyist and make great additions to any tank . i have never had the pleasure of keeping this shrimp so much of this information is gleaned from deferent sources across the internet . i would greatly appreciate any comments you have on the care and keeping of these fine animals .
body color consists mostly of a light brown opaque color . on the back shell , there is a tan stripe that runs from the head down to its tail . on the shrimp ' s side flanks , are a series of broken lateral lines that are a reddish - brown in color . the tail also contain two or more black and white dots .
the amano shrimp is difficult to breed . i have read that there have only been a few people who have managed to breed these shrimp , and even fewer who have managed to raise the fry . it is believed that the mating season lies in late spring or early summer . if fry are produced , they should be removed from the parents , and should be kept in an aquarium with a sponge filter and plenty of algae to eat .
please remember that the following comments are personal experiences and may or may not apply to your setup . use them as guide to help better understand your fish , like us all individuals will behave differently under different circumstances .
amano shrimp life span is 10 + years , if taken good care . my little amano - girl is 11 years old . the other lived 9 years . shrimp - only tank , walstad or natural tank method ( no water change , heavily planted tank ) , minimal feeding ( once a week or even less ) , cooler water ( 18 - 22 degrees c ) . it seems such conditions like her : )
i have four of these in a 20 gallon brackish ( sg = 1 . 005 ) tank with two mollies and four guppies . i have had them for about six months now , and i have been very happy with them . they are a very good algae eater for a peaceful brackish setup . i add a couple drops of iodine once a month and have had no molting issues . they mainly eat the same plant - based food that the mollies eat , and also enjoy a chunk on algae wafer once a week .
i ' ve had my pair of amano shrimp for almost 6 months now . they molt at least once a month , sometimes twice a month . they enjoy most kinds of algae but don ' t expect a few of them to end your algae troubles . they also enjoy scraps of flake , frozen meaty food , sinking wafers , just about anything . mine fight over shrimp pellets ! great for any tank as long as they won ' t be eaten , live comfortably in just about any situation , are easy on the eyes , and fun to watch .
i am new to these shrimp . i bought six for my lidless mini hex , but they all jumped out . in addition to not having a lid , the small space crowded with fish made them extremely jumpy . it ' s possible they climbed out , but i suspect they jumped . i got a new , lidded , 20 gallon and i am shocked to see that all five new guys are still alive and well after a week . i have five ghost shrimp that hang out on the bottom , but so far the five amano shrimp are comparatively shy , hanging out mostly in the small baby water hyacinth floating at the top .
i bought 8 amano shrimp in feb 2001 . i still have 4 buzzing around the tank today ( april 2007 ) . hardy things . i love watching them ' swim ' across open water by racing their little legs like cartoon characters . they can shift too ! but if you have a sickly fish in with them , you need to get it into another tank fast else the shrimp will likely finish it off leaving you with nothing but a sad little skeleton .
i bought these for my daughter and they keep her community tank clean . so i bought a few more and kept them in my hospital tank which used to suffer terribly from algae . several sick fish later , they are still there and doing a great job
i have been able to breed and raise these little guys in a planted tank for about a year now . very dense plants , ph is controlled by co2 to be about 7 . 0 . they are kept with german blue rams so i ' m sure i ' ve lost many . really haven ' t done anything special to get this result . amazing clean - up crew ! ! !
kept these for the last year , ph of 8 , nitrate 40ppm . can ' t seem to stop them producing eggs . excellent species to help keep algae levels low , perfect for a community tank .
these little guys have kept my tank very clean and are fairly strong . here in japan , the water is very hard and is difficult to maintain steady ph levels . they are true survivors !
as cool as these are , and the ease of caring for them , they are best kept away from many loach species . i had 2 of these shrimp and my blue loaches seemed to have gotten fatter while there was not even a piece of shrimp remains in the tank . just a lil hint of caution .
got 2 . very shy when first introduced to tank ; kept hiding and even jumped out of tank when i was away . luckily 1 survived after several minutes outside . now very outgoing in community tank of tetras and livebearers sheds old skin after every major water change . prefers leftovers over algae . entertaining - must get some more !

nathan hill explores the origins , benefits and breeding of one of the hobbyâ€™s biggest game changers , the amano shrimp .
i’m not sure aquascaper takashi amano realised just how much he’d change the face of fishkeeping when he asked a local collector to round up a few thousand bland , colourless shrimp for him . now , three decades on , there are few tanks that haven’t felt the presence of these hard - working , tenacious invertebrates .
my own experiences with these fastidious grazers have been positive through and through . they’ve saved aquascapes as well as my large retail displays ( in my aquatic store manager days ) and i’ve even had them breed , which is something i didn’t know was remarkable at the time and something that many amano shrimp adherents will vehemently deny ; more on that later .
if ' japonica ' sounds a little far eastern to you , then you’re on the right track . this name refers to their japanese heritage , where takashi came across them and where many come from today . the original specimens were recorded from the ogasawara ( or bonin ) islands , though they’re just as happy on mainland japan too .
there are even hints of an indonesian variant doing the rounds , but these are also contested on a species level ; they have a straight rostrum and not a crested one . buyers beware , and be diligent . true amano shrimp should be relentless workers , and that’s exactly what fuels their popularity . tirelessly padding away with their tiny maxillipeds , they will graze on almost all forms of algae with just the dreaded black beard algae and some cyanobacteria types being sometimes averse to their palates .
lacking cutting or biting mouthparts , at best they can softly rasp away at surfaces taking away the topmost film . this inability to cause harm makes them ideal workers in tanks where there are small fish and even fry , which they will largely ignore . my own experiences have seen the occasional , bold amano tootling off with a prize in the form of a fish egg , but their impacts on breeding populations are negligible at best .
some aquascapers have griped and bickered that their amanos have damaged planting , but this is unfair condemnation . amano shrimp will indeed rasp away at plants but are only able to take away material that is already dead or dying . it’s not unusual to find perfectly cut holes in leaves , where plants have degraded through nutrient deficiencies and the shrimp have cleaned the site up . much like maggots in a wound , they’ll only eat the bad and leave the healthy .
the benefit to the aquarist in keeping these shrimp is huge . their eating efficiency and digestive capacity is second to none , and , in part , a reaction to what can be an oligotrophic lifestyle .
in the aquarium they will pick up on almost any waste , be it uneaten food , fish faeces , decaying plants , or whatever , and convert it into tiny packages of shrimp waste , almost like large grains of jet black sand . these can then be easily siphoned from the tank during a water change .
regardless of how good a cleaner they are , remember that amano shrimp do not impact on nitrate levels at all . it does not matter if you have ten or two hundred of them , you’ll still need to water - change just as frequently !
there’s little reason to consider a biotope for these creatures , but if the idea appeals then simply go in for a large tank with big rocks and boulders inside it . alternatively , amano shrimp can be found in swamps with a handful of mossy plants and organic litter .
don’t be scared of a little turbulence either . in their natural range , amano shrimp are often subject to middling to strong flows and have a better grip on surfaces than you might expect .
as well as ammonia and nitrite , heavy metals should be avoided so remove any rocks with striated lines of metal through them and avoid lead weights for plants . although these become issues in mainly softer , acidic water , even in hard systems they can form dangerous levels .
aquascapers are occasionally worried about the heavy metals found in plant nutrients , but to my knowledge there is no credible evidence that even a major overdose of ferts causes health issues or fatalities in amano shrimp .
avoid salt , too . though this chemical is essential for the rearing of larval shrimp , the adults have no tolerance of it and even background levels used as tonics ( 3g per litre ) can be lethal to them . hardness needn’t be high , but gh should not be below 6° for successful moulting . temperatures are tolerated between 18 and 27°c / 64 . 4°f and 80 . 6°f , and fluctuations between day and night largely ignored .
one area of caution is the use of co2 , especially where amanos are in planted tanks . excess co2 will drive the ph down , and below 6 . 0ph they will struggle .
the biggest danger to your shrimp is poisoning , especially from airborne insecticides and more so from imported aquarium plants that haven’t been properly rinsed . subjected to these chemicals , shrimp will rapidly turn from transparent to white and / or pink and lose all composure and momentum . shortly afterwards they will be immobile on the base of the tank with only their tiny pleopods twitching , and then they will die . there is no cure for poisoning once it takes hold , so avoidance is the only sure course .
keep them correctly and you can expect a lifespan of up to four years from your shrimp , over which time they can reach up to 5cm / 2
in length .
filtration for amano shrimp needs to be unable to suck them in , but they also benefit from having access to sponge filter media where they will nibble at the biofilm and waste contained within . foam , air - powered filters are a good choice , but better still is the hamburg mat . this involves placing an entire sheet of foam within two guide rails to create a filter ' wall ' . an uplift is then placed behind the mat , just like the uplift of an undergravel filter , and water pulled through the foam and back over the top into the tank .
hamburgs provide a huge filtration surface , as well as an ongoing source of food for shrimp , and cost pennies to put together . your local aquatic store can likely give you more advice and the parts required to put one together if you choose .
all crustaceans need to shed their shell in order to grow , and this stage is called moulting . shrimp moult more when they are younger and , subsequently , growing faster , though adults may moult on around a monthly basis . this also helps to keep the shell healthy and free of pathogens .
with insufficient gh in the water , moulting is impaired . some keepers rattle sabres over whether or not to leave the shell in the tank once the shrimp has shed .
in theory , the shrimp will ingest some of their own shells and regain some of the valuable chitin within . but in reality if diet is appropriate and gh levels adequate , then this will be surplus to requirements .
that said , there’s no harm in leaving the shell in the tank for grazing purposes .
people often ask what the difference is between a prawn and a shrimp , and everyone likes to hold a pet theory about what constitutes each .
in reality there is no difference between the two words , and they are arbitrarily assigned to whatever takes the whim of the user . scientifically the two names carry no meaning , so you should feel free to call your own tank inhabitants a troupe of amano prawns if that’s what you prefer . so there you have it . prawn and shrimp are common names , which vary considerably depending on where you are .
if you’re in america you might be sold prawn as shrimp , and in the uk you’ll get the reverse but it’s nothing deeper than that .
shrimp belong to the order decapoda , like crabs and lobsters . the common feature between them is that their ancestral progenitor had , at some stage , ten pairs of legs .
looking at a shrimp it might appear obvious that nowadays they have anything but ten pairs , but the point still holds . they have just adapted and changed the forms and roles of their legs , so that the ten pairs are now divided up between the pereopods , or walking legs , and maxillipeds , or mouthpart legs . the swimming legs , the pleopods , at the rear end are a different matter altogether and are not classed as legs in the same sense .
most medications come with clear warnings that they shouldn’t be used with shrimp and for good reason . anything containing copper compounds is lethal to crustaceans and needs to be avoided .
the reason it is so dangerous is down to the blood of the shrimp . we humans use haemoglobin , which is basically iron that makes up our blood cells , to carry our oxygen around . crustaceans , however , have blood cells made up of haemocyanin , which uses copper instead of iron to carry oxygen . when using copper - based medications this blood is affected , ruining the crustacean’s ability to ventilate .
some keepers are reluctant to use water that has been stored in a hot water tank or run through copper piping for fear of contamination , though this only tends to be reported as an issue in new plumbing systems that have not had the chance to calcify inside . an offshoot of having copper - based blood is that unlike our own , which is red , in shrimp and other crustaceans it is blue .
wild shrimp live coastally , where they release their young downstream into the sea . after some four to five weeks , during which the zoea frequently moult and fatten up on plankton , they become parva , which move back upstream to restart their lives in freshwater mode . this explains their distribution over so many sea bound islands . as the females become increasingly pregnant ( or berried ) they will show a telltale darkening in the first segment of their abdomens .
my own amano shrimp bred more by extreme coincidence than skill of any kind . kept in a 120cm / 47 . 2
cube tank with diabolically slow flow , the tank and adjoining system would be periodically treated with salt to help new arrival fish .
other diligent breeders have had stabs at breeding amanos , usually involving a separate larval system rigged up with seawater , with mixed success . it’s certainly possible to do , but unless you’ve got something close to lab - grade facilities , including plankton sources , then i wouldn’t hold out too much hope for you !

this particular species of shrimp is indigenous to east asia . they are known to inhabit mainland japan , taiwan , the ryuku islands and the korean peninsula . the first person to rear them on a commercial basis in captivity was the famous japanese aquarium enthusiast takashi amano .
the male has a row of distinct dots along its lower side . the female has this row as more of a broken line , and is also slightly bigger . see picture below .
they are renown for being algae eaters but when keeping them in larger groups , it is typically essential to provide them with extra food . like other species of dwarf shrimp , the amano shrimp will eagerly accept food formulated for for bottom feeding fish and any aquatic invertebrates .
as is their correct name ) as well as special feeding . breeding of this species is considered fairly difficult as the zoes need to be gradually introduced to salt water and then back to freshwater . see external link below .
has postulated that perhaps 1 in 100 , 000 zoes may survive to adulthood in freshwater if the water chemistry is hard enough and this may be what aquarists have been seeing .
the amano shrimp prefers planted aquariums . slightly soft ( gh 6 - 10dh ) water is preferred ( if the gh is too low they can ' t make their
, and as such should only be added to a cycled tank . a small level of
in the water is recommended to help them moult . this can be supplied via normal fish food or via typical health food shop kelp tablets .
like most shrimp any presence of copper in the water ( bar background traces ) will kill them .
a tank of at least 10 - 19 litres ( 2 . 6 - 5
) is considered the minimum and you can stock around one shrimp per 3 - 5 litres ( 0 . 8 - 1 . 3
. it should be noted , however , that they generally prefer fish food to algae , and will only resort to the latter if the former is unavailable . also , due to their small size , a large number of them may have to be employed to make a serious impact .
if you see your shrimps at the surface a lot then this is probably due to lack of oxygen or high nitrate levels .
approximately once a month ( depending on diet , age , and environmental factors ) , the shrimp will moult . during this time , the shrimp will seek out a place to hide while its new shell hardens , for safety reasons . many inexperienced aquarists jump to conclusions , assuming their unseen shrimp to have been eaten ; these fears are short lived however , as they usually reappear after a few days .
although mostly peaceful in temperament , amano shrimp can nevertheless be rather greedy feeders . while they refrain from attacking other aquarium inhabitants , they will not hesitate to steal food from smaller shrimp . in the absence of predators within the aquarium environment , amano shrimp will take on a rather active role , foraging and cleaning the aquarium of algae

they grow about twice as large as dwarf shrimp , attaining a maximum size of over two inches ! their bodies are translucent with a bluish tint , and are covered in small , dark red dots .
amano shrimp are totally peaceful , and are great additions to shrimp tanks with other dwarf shrimp species as they will not interbreed with other dwarf shrimp or eat shrimp fry .
other types of dwarf shrimp ( such as blue velvet shrimp , sakura fire red cherry shrimp , neon yellow shrimp , etc . ) , various types of snails ( such as nerite snails , sulawesi snails , etc . ) . they can also be kept with small to medium - sized , non - aggressive fish .

i was a little skeptical ordering shrimp off amazon , but they arrived well packaged , well insulated , and all alive . these little shrimp are a blast to watch . they ' re extremely fast swimmers - they can go backwards as well as forwards - but mostly they herd together and graze on algae . they ' ve formed a colony on top of one of my powerheads , but they do come down and wander around the aquarium feeding .
last year i bought amano shrimp from aquatic arts . most of them are still alive and the females constantly have eggs . which is a little sad because they cannot mature in freshwater . i have bought inverts from ebay sellers before but aquatic arts always has high quality animals and service . they even fulfilled my request for larger shrimp since i was solving a scud infestation with hungry fish at the time and did not want to risk losses on juvenile shrimp . i have bought amanos several times , as well as some of their snails and highly recommend this seller .
best algae eating aquarium shrimp . they even eat black beard algae , never have an algae problem again . they are the hardest freshwater shrimp in the aquarium hobby , much hardier than cherry shrimp and crystal bee shrimp . i ordered mine on monday and arrived at my home thursday in the same week . i have ordered many items from aquatic arts , they are great .
i was very impressed with the communication from the sellers . they were concerned about the heat index where i live ( as was i ) and monitored it daily until it was safe to ship the shrimp . i definitely appreciated this . as a result all of them arrived alive . i keep these as pets along with cherry reds that i also bought from this seller . several have already molted and i ' ve seen a very tiny one swimming around that was not present with the group when they arrived ( baby ? ? i don ' t know . ) they are thriving and i could not be happier . they are so much fun watch ! i recommend this seller !
these shrimp all seemed healthy on arrival , but all died within 24 hours . the ammonia and nitrites in our 90 gallon tank were zero , and the nitrates below 0 . 25 . all the snails we received in the same order have thrived , and we have successfully kept amano shrimp in this tank in the past , so not entirely sure what went wrong here . the sellers , however , were very responsive and concerned , and replaced the 5 cherry shrimp in the order that were doa , so this may just have been an unfortunate shipping incident .
the amano ' s all arrived alive and healthy , but unfortunately they came with some pest snails too .
arrived a day early . alive and very active . acclimated well and are doing great . great company .
have a 210 heavily planted tank and have had trouble finding amani ' s in dallas . shrimp came as advertised . admittedly a bit smaller than expected . only one dead on arrival .
amano shrimp arrived alive and safely packaged . acclimating them to the new aquarium was simple with the included instructions . so far , all seems active and happy in the new home .
these shrimp are very active and fun to watch . my third purchase with aquatic arts and i have yet to be dissapointed . i highly recommend aquatic arts .
they live ! ! and they ' re doing their job in my 55g tank with a school of zebra danio ' s floating around . happy ! !

liocoris is a genus of plant bugs belonging to the family miridae , subfamily mirinae .

it has only one species .

in 1955 it was briefly considered as the home of the " lygus bugs " due to the morphological studies of kelton , but the decision of the international commission on zoological nomenclature ( iczn ) in 1963 allowed them to stay in genus lygus .

the species that kenton described in 1955 as liocoris are now classified as lygus .

liocoris

liocoris tripustulatus schwartz and foottit 1998a : 368 , fig . 458 - - 471
kelton , leonard a . 1955 . species of lygus , liocoris , and their allies in the prairie provinces of canada ( hemiptera : miridae ) . the canadian entomologist , vol . 87 , issue . 12 , p . 531 .
this bug doesn ' t care about its surroundings . as long as there ' s nettle , it will be around . so you ' ll find in woods , along wooods , in gardens , parks , wastelands and in the center of cities . liocoris tripustulatus can be found all over europe , the near and middel east , western asia and the caucasus . it is a very common and often even abundant species all over britain .
liocoris tripustulatus is a small , but beautiful bug . the scutellum is decorated with a heart shaped marking . just like the two spots in the wings and the snout the colouring of the heart is variable : from whitish yellow to deep orange . there also is a more or less visible band running over the body from side to side about halfway . this band often is orange or brownish . like in many other bugs , the legs are spickled . the insect reaches a length between 3 . 5 and 5mm .
the eggs are being laid in april and hatch in may . the larvae are not very similar to their parents , for they are green entirely . the larvae live on nettle only . they suck on the flowers especially . the first adults are seen in july . they may also been seen on many other plants . it is unclear however whether they also suck on these other plants or on nettles exclusively . the adults live for a rather long time , for there is only one brood each year . adult liocoris tripustulatus overwinter . during this time they hide between leaflitter , behind loose bark or in holes in trees made by wood drilling animals .

common throughout the uk and associated mainly with nettles , the foodplant for all life stages , this is a variable but distinctive species . the colour of the scutellum and cuneus ranges from cream to deep yellow and the pale legs are striped with black rings . short dark spines are present on the tibiae . head width
this bug may be found as an adult all year , and variation in colour is strongly related to age . on spring emergence following hibernation , the ground colour is typically darker and the cuneus more orange - yellow . following mating , females may survive until the new generation of adults appears in mid - summer , which is generally paler and less intensely marked .

corresponds to a report on the basis of at least one observation proved within a period of 10 years ( 20 years for little - known invertebrates ) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population . for migratory species , the presence indicated concerns areas of reproduction .
the last reliable sighting is older than 10 years compared to the reference date , no recent specific research and no presumption of extinction from that date [ vertebrates , invertebrates and plants well studied ( rhopalocera , grasshoppers , dragonflies . . . ) ] ;
the last reliable observation being older than 20 years , no recent specific research and no presumption of extinction from that date [ poorly known taxa : fungus , many invertebrates . . . ] .
this point covers the absence , more difficult by nature to demonstrate than presence . this status is based on one or more of the following criteria :
this status must be assigned to a department in which the presence of the species is casual .
particular case of absence due to a proven extinction less than a half century ago ( older disappearances are treated as
no probable or definite
) .
in the state of knowledge , we can not comment on the presence or absence in the current department . this is the default status when not comprised in one of the previous categories or whenever there is doubt .
warning : the data available reflects the progression status of knowledge or the availability of the inventories . it should never be considered as comprehensive .
