the speckled pigeon ( columba guinea ) , or ( african ) rock pigeon , is a pigeon that is a resident breeding bird in much of africa south of the sahara .

it is a common and widespread species in open habitats over much of its range , although there are sizable gaps in its distribution .

this species builds a large stick nest on protected rocky outcrops and in urban areas often atop covered pergola pillars and on flat roofs under deep eaves and lays two white eggs .

its flight is quick , with regular beats and an occasional sharp flick of the wings that are characteristic of pigeons in general .

this is a large pigeon at 41 cm in length .

its back and wings are rufous , the latter heavily speckled with white spots .

the rest of the upperparts and underparts are blue-grey , and the head is grey with red patches around the eye .

the neck is brownish , streaked with white , and the legs are red .

the call is a loud doo-doo-doo .

sexes are similar , but immatures are browner than adults and lack the red eye patches .

the speckled pigeon is frequently seen around human habitation and cultivation .

most of its food is vegetable , and it gathers in large numbers where grain or groundnuts are available .

protection / threats / status : speckled pigeon is common throughout most of its range . populations are stable or increasing .
behaviour : speckled pigeon gather in large numbers where grain or groundnuts are abundant . it is very gregarious and flocks may reach several hundreds of birds , mixed with other pigeon’s species and doves . they roost on cliffs , buildings and tall trees . speckled pigeon walks and runs easily on the ground .
range : speckled pigeon is resident in most parts of africa south of the sahara . it is scarcer in central parts .

voice : sounds by xeno - canto speckled pigeon gives loud , explosive cooing “doo doo doo” or “whu whu whu whu - whu” uttered with force and volume .
the speckled , or african rock , pigeon is not a threatened species . zoos keep it primarily for educational reasons , e . g . in the context of mixed african savanna or mountain exhibits .
flight : speckled pigeon has strong flight , and it often flies very high in the sky . it has fast flight with regular wing beats . in flight , pale grey rump contrasts with darker upperparts .
speckled pigeons feed on seeds , grains and groundnuts , and are especially fond of seeds that have newly germinated .
response : this is a speckled pigeon , columba guinea , a species that is placed into columbidae , the pigeons and doves . speckled pigeons are endemic to most of sub - saharan africa . they are common residents of open country , savannahs and grasslands that have either rocks and cliff ledges or tall trees . they also are found near human habitations and on farmland .
speckled pigeon breeds year - round in most parts of its range . when pair is formed , male attracts its mate into potential nest - site by some postures such as crouching down , lowering the head and twitching its wings . at the same time , it utters vocalizes .
habitat : speckled pigeon lives mainly in open country , farmland , savannahs , grasslands , with nearby trees such as palms or baobabs . it is also found in urban areas where it is often seen on roof tops . it may lives from sea - level to 3 , 000 metres of elevation .
the speckled or african rock pigeon is about the size of a feral pigeon . it reaches a total length of 33 cm and a body - weight of 315 to 390 g . males are more powerfully built than females the plumage is bluish grey on crown and neck , and cinnamon - brown on sides of neck , mantle and wing coverts . feathers on neck and upper chest are tipped metallic and pale green . there are obvious white speckles on the wings , otherwise the plumage is various shades of grey . the iris is yellowish - white , the bill blackish and the cere whitish . the bare skin around the eye , and the legs , are red , which is distinctive . the speckled pigeon breeds all year round . the nest is a platform of twigs and roots . the female lays usually two eggs , which are white and glossy , and measuring 37 x 28 mm . the clutch is incubated by both parents for about 14 - 16 days . the chicks fledge at an age of about 25 days . speckled pigeons are usually seen in pairs but may congregate to large flocks of several hundreds when not breeding . the speckled pigeon feeds largely on seeds and grain , including spiky seeds such as “duiweltjie doring” ( tribulus ) .
distribution of speckled pigeon in southern africa , based on statistical smoothing of the records from first sa bird atlas project ( © animal demography unit , university of cape town ; smoothing by birgit erni and francesca little ) . colours range from dark blue ( most common ) through to yellow ( least common ) . see here for the latest distribution from the sabap2 .
reproduction : speckled pigeon breeds mainly in latter half of dry season . it may nest singly or in colonies . nest is situated on a cliff , in tree or in building . we can find various kinds of constructions , such as scrapes , or loose cup with a few twigs , or even large platform of twigs . interior is lined with small twigs or grass .
similar species : african olive pigeon ( columba arquatrix ) from ethiopia to the cape . it has the same dark maroon upperparts and white spots , but it has yellow orbital skin , bill and legs . feral pigeon ( columba livia ) from southern edges of sahara and sahel region . some varieties may be similar in plumage , but they often lack the red orbital skin .

speckled pigeon are gregarious and flexible breeders , breeding the year round and nesting singly or in colonies . the nest is a large and untidy structure that is constructed on a cliff , in a tall tree or on a building . both parents share incubation and chick tending duties . the pigeons have a special reproductive innovation known as crop milk . this nutritious substance in secreted by the lining of the crop of both parents and is fed to the nestlings . crop milk is also produced by flamingos and some penguins .
did you know ? that in spite of its name
rock pigeon
this species does not need cliffs for nesting ? it has become a very urban species nesting on houses , and may also nest in major forks of a tree or even in disued agricultural machinery .
we find three other races : columba guinea phaeonotus , from ne zimbabwe and sw angola to the cape . this one has darker grey head and rump . white triangular spots on wings are smaller . this pigeon is slightly larger . and two more : columba guinea guinea and columba guinea rufina .
the speckled pigeon is common in many places in southern africa , especially in south africa . it usually lives in rocky , mountainous areas , but can also be found in buildings and gardens . it feeds mostly on seeds , rarely eating small fruits and flowers . the nest is usually placed on ledges , gullies or buildings , and is built by the female , with the male collecting the material . it lays 1 - 3 eggs , which are incubated by both sexes . the chicks are brooded for the first 6 days of their lives , after which brooding ceases . the nestling period is highly variable with different regions , full range 21 - 37 days .
this species is fairly distinctive . upperparts are bluish - grey and the mantle is maroon with light purple iridescence . the head is grey with bare red skin patches around the yellow eyes and the bill is dark with a white cere . the brownish neck is streaked with white , and the feet and legs are pink . the upperside of the wings is dark rufous - brown and coverts have white triangles on the tips , giving the bird its distinctive speckled appearance . the tail is dark grey with a broad black terminal band . in flight , the pale grey rump contrasts with the darker upperparts . underparts are a pale grey . both sexes are similar and juveniles are browner and duller than adults .

psaltoda plaga is a species of cicada native to eastern australia , from maryborough in central queensland to bega in southern new south wales .

adult cicadas appear over the summer and inhabit forested areas near bodies of water .

the predominantly black form from the sydney and central coast regions is commonly known as the black prince , while the term silver knight is used for the species as a whole .

psaltoda plaga

here is an elderly black prince ( psaltoda plaga ) found in our permaculture garden as he was lying in his death roes .
psaltoda plaga , commonly known as the
black prince
, an australian species of cicada which emerges once every 7 years .
probably the best known and most mysterious is the black prince ( psaltoda plaga ) followed closely by the green grocer ( cyclochila australasiae ) . other popular names include the double drummer ( thopha saccata ) , cherrynose ( macrotristria angularis ) , floury baker ( abricta curvicosta ) and redeye ( psaltoda moerens ) .
december 18 , 2017 : razor grinders ( aleeta curvicosta ) and redeye cicadas ( psaltoda moerens ) , reported by mike young on facebook .
cicadas are so conspicuous that many of their common names were initially given to them by children . as a result cicadas probably have the most colourful common names in the insect world . some of these include : black prince ( psaltoda plaga ) , double drummer , floury baker , and the green grocer or yellow monday , cyclochila australasiae .

summer is filled with the deafening drone of cicadas that bear exotic names like the black prince , green grocers , yellow mondays , floury bakers , and red eyes .
the green grocer cicada gives australian cities a distinctive summer - time buzz . ( source : australian museum )
there are just under 2000 species of cicada around the world . in australia around 220 species have been identified , most of which belong to the one large cicadidae family .
their sudden appearance in the summer months , mysterious feeding habits and striking song have attracted attention to cicadas for thousands of years . most children in australia have climbed backyard trees to collect these noisy insects and kept them in an old shoe box lined with leaves .
they don ' t bite , they aren ' t regarded as a pest and they ' re harmless to humans . but there ' s a lot more to our shrill summertime visitors than meets the eye .
the common names for cicadas vary widely around the world . in australia , children were the first to coin the common name for many cicadas , names that have been dutifully passed down from generation to generation of cicada hunters .
two other common names becoming more widely accepted are bladder cicada ( cystosoma saundersii ) and hairy cicada ( tettigarcta tomentosa and t . crinita ) . the exact origin of most of these names is unclear , but the yellow monday and green grocer were in popular use as early as 1896 .
when : green grocers tend to come out early in november and die out by the end of december . black princes and floury bakers start off at the end of december and go right through to february or march , while red eyes can still be found in the middle of february .
where : cicadas occur in almost every part of australia however , cicadas are primarily tropical insects and most australian species are found in the northern half of the continent .
the yellow monday was given its common name by australian children . ( source : australian museum )
no matter how many summer holidays you spent collecting every variety of cicada , there ' s a few things you probably still don ' t know about them .
australian cities are some of the very few in the world to experience the loud singing of cicada song right in the middle of suburbia .
this is because the green grocer is unusual in its ability to adapt perfectly to the urbanised environment according to australia ' s foremost expert on the cicada , dr max moulds from the australian museum in sydney .
when people come here from europe and america they are amazed , they have never heard anything like it before ,
dr moulds said .
because the green grocer has adapted to cities like sydney and melbourne , and because they are so loud and obvious , cicada song gives our cities a summertime buzz distinct from most other cities around the world .
another little - known fact is that cicadas suffer from insect vd . dr moulds said the adults of some cicada species are susceptible to fungi of the genus massospora .
these entomopathogenic fungi attack the terminal portion of their abdominal cavity and genitalia - a cicada venereal disease if you like ,
dr moulds said .
it is a fungus unique to cicadas and it usually makes their tail ends drop off .
most australians are also probably unaware that the cicada can make a very tasty meal . dr moulds said many peoples around the world regularly eat cicadas , usually as an addition to their regular diet .
they are quite good eating and taste quite pleasant ,
said dr moulds who sampled his first roasted cicada during a field trip in papua new guinea .
the female cicada is usually best because they are the most meaty . first they pull the wings off and then throw them onto hot coals for about a minute . turn them over once or twice and they ' re ready to eat . i thought they would be crunchy but actually they are remarkably soft . their taste is not very strong and is probably closer to chicken than anything else .
if you can ' t bring yourself to add lightly roasted cicada to the menu , perhaps you ' d prefer to keep one as a pet for a day or so instead .
cicadas do make good pets for children because they are small , harmless and don ' t make any mess . however , it ' s difficult to keep them alive for more than a day or two in captivity because they need flowing sap from a tree to feed on for survival ( see
the cicada ' s lifecycle
below ) .
dr moulds said the only way to keep them alive in captivity is to cut a ' fairly substantial branch ' from the tree you find them in and put the exposed end in water to keep the sap flowing . the branch would then need to be changed at least every second day to keep them fed .
this is quite a difficult process , so it ' s probably better just to observe them for a few hours , perhaps up to a day , and then let them go again ,
dr moulds said .
cicadas are the most efficient and loudest sound - producing insects in existence . while dr moulds said nobody is exactly sure which species is the loudest , he said the green grocer
must be close
.
the green grocer , yellow monday and the double drummer produce noise intensity in excess of 120db at close range ( this is approaching the pain threshold of the human ear ) . some small species , on the other hand , have songs so high in pitch that the noise is beyond the range of our hearing .
only the male sings as a mating ritual to attract the females and different species have different songs so they don ' t attract the wrong females . cicadas are different to all other insects in that they actually have a musical drum in their abdomen .
the organs that produce sound are the tymbals — a pair of ribbed membranes at the base of the abdomen . contracting the internal tymbal muscles causes the tymbals to buckle inwards and produce a pulse of sound . by relaxing these muscles , the tymbals pop back to their original position . the inside of the male abdomen is substantially hollow to amplify the sound as it resonates at the frequency of the call .
the loud noise produced by some cicadas actually repels birds . the males of many cicada species tend to group together when calling which increases the total volume of noise and reduces the chances of being eaten by birds .
in addition to the calling or mating song , many species also possess a distress song , usually a broken and erratic noise emitted when an individual is captured . a number of species also have a courtship song , which is usually a quiet call produced only after a female has been attracted nearby using the calling song .
top view of a green grocer nymph breaking free from its shell . ( source : austrlian museum )
there are three distinct stages in the life cycle of a cicada : egg , nymph and adult .
egg stage : after mating , the female will lay several hundred eggs . she makes a little slit in the bark of the branch as she walks along and pushes the eggs down through her long tail . she deposits 12 or so into each slit and then moves on a few millimetres to make another slit for more eggs , and so on , until all the eggs have been laid .
nymph stage : the eggs stay in the slits in the bark for many weeks and then hatch into a miniature cicada called a nymph .
because they are so small they can fall down to the ground without injuring themselves and seek shelter underneath the leaf litter .
they search for cracks and burrow down between 10cm and 40cm using their large forelegs to shovel soil around . it ' s here , underground , that cicadas spend most of their life . the cicada nymph feeds by piercing small tree roots with its needle - like rostrum and sucking up sap . when the sap runs out , it tunnels around to find a new root to feed from . while living and feeding underground they continue growing , periodically shedding their skin , until they reach maturity .
adult stage : when the nymph finally reaches full size it digs its way to the surface , climbs on to a tree trunk and sheds its skin for the last time leaving a telltale brown shell . the life of the adult , in contrast to that of the nymph , is very short .
when they emerge from the ground they live for varying periods of time , from a few days to a couple of months , depending on the species . the majority live for around two to four weeks during which time they mate and lay eggs and the cycle starts again .
while it is true that most species take around six or seven years to re - emerge , dr max moulds said their underground sojourn can take anything from nine months to 17 years or more depending on the species .
nobody really knows exactly what it is that tells cicadas when to emerge from the ground ,
dr moulds said .
it ' s most likely to be a combination of events or signals , one of which would be increased sap flow in the tree indicating that warm weather and rain is around .
when you have a year with thousands of cicadas out you are likely to have another year in five to seven years time when there are similarly large numbers . but this is by no means certain .
the eggs take quite a few weeks to hatch and if there are unfavourable conditions while they are hatching many will die . if the seasons are good and the trees are doing well they might come out in just five years . even eggs from the same batch will come out in different years , so there ' s lots of variability involved ,
dr moulds said .
a famous urban legend is that a chemist will pay good money for the wings of the elusive black prince cicada . and what do they do with the wings ? they crush them up to make medicine of course ! though the exact type of medicine is never really specified .
this urban myth may have its origin in truth of sorts according to dr moulds .
while you ' d be hard pressed to find a chemist that would part with good money for even the rarest cicada wings , this legend probably came from the gold rush days when there were many chinese entering the country ,
dr moulds said .
traditional chinese herbal medicine made use of cicadas for a variety of medical purposes . they believed they could do all sorts of things for you if you ate them or crushed them up to make a poultice .
cicadas were used as a diuretic by peasants in provence and as a cure for earache in china and japan . the chinese commonly use an unusual black and red coloured species ( huechys sanguinea ) for a variety of medicinal purposes .
a second black prince myth is that they are extremely rare and difficult to find . this actually isn ' t the case , according to dr moulds .
it is true that they are not very common in the city and suburban areas of our major cities , but that ' s only because they live and breed in she - oaks which are commonly found on river banks ,
dr moulds said .
this means they are actually quite abundant if you look in the right places , such as next to rivers in rural areas around the major cities .
to the ancient greeks the cicada symbolised resurrection , rebirth and immortality and is mentioned as being sacred to the ancient greek sun god apollo . homer mentions cicadas in the iliad around 900 bc and compares the discourse of
sage chiefs exempt from war
to the song of the cicada .
ancient greeks and chinese made a habit of keeping male cicadas in cages for the pleasure of hearing them sing . one greek ode to the cicada says :
we call you happy , o cicada , because after you have drunk a little dew in the treetops you sing like a queen
.
cicadas also had a powerful effect on artists as they feature on numerous coins both before and after the time of christ . a number of beautiful gems have also been found from around 300 bc carved in the likeness of the cicada . the cicada ' s emergence from the earth was a powerful symbol for ancient romans with members of the nobility taking to wearing a gold brooch featuring a cicada to hold back their hair .
in taoism the cicada is the symbol of the hsien , or soul , disengaging itself from the body at death . cicadas also feature in japanese carvings on small medicine boxes and they are mentioned in ancient hindu law as long ago as 200 bc in india .
cicadas occur in almost every part of australia , from the hot and wet tropical north to the snowfields of tasmania , from beach sand dunes to the driest desert . the plants they inhabit range from the tallest trees to suburban lawns , coastal mangroves to desert shrubs and include both native and exotic plant species .
however , cicadas are primarily tropical insects and most australian species are found in the northern half of the continent . the great variety of vegetation types and local climatic variation found in north - eastern queensland makes this the richest region for species . the area of greatest species diversity is within 100km of cairns .
the time at which cicadas appear throughout the summer season varies from species to species , but each will tend to emerge in the same month across the different states . green grocers tend to come out early in november and die out by the end of december . black princes and floury bakers start off at the end of december and go right through to february or march , while red eyes can still be found in the middle of february .

laura imbruglia sings songs that mention green grocers and yellow mondays on her album “it makes a crunchy noise” .
we live on a farm at lorne just outside kendall nsw and the cicadas have been deafening this summer . interestingly i have found no bladder cicadas this year and very few green grocers all the other varieties have been in abundance though . my granddaughters have had a marvellous time collecting and identifying them .
hello . we have just returned from a couple of days camping on a property we have bought up near gloucester / barrington tops in nsw . the noise from the cicadas was deafening . i’m wondering if you might be able to tell me which species they are likely to be in that area and if they they are likely to sing so loudly and in such large numbers in future years . many thanks .
the loudest species is the double drummer / thopha saccata — might be that . see urltoken for a sound sample .
plenty of floury bakers in the lower blue mountains right now . one flew in my car window as i was driving . it hit my shoulder and flew into the back seat . upon recovering it , i noticed that its abdomen had popped off quite neatly . the poor bloke was still very much alive 6 hours later . is this some kind of defense , like skinks dropping their tails ?
we just moved to artarmon area , very near to the station , and was surprised to hear the loud singing of cicadas . though it might be music to some , i wanna know when do they stop . and are they dangerous ? my 3yo often go around them . thanks !
they aren’t dangerous in that they’re not venomous not do they transmit disease . prolonged exposure to their song might cause hearing damage though . double drummers can get up around 120db . definitely don’t put one up to your ear .
just recorded some video of an absolute plague of floury baker , and what i thought were black princes , but after looking at some photos on this site i now think may be red eye , cicadas in my backyard at elanora heights , on sydney’s northern beaches . urltoken
missing is the black prince which was almost mythical and the dream of each kid to find one ( i did it was very small ) . the female green grocers were called “pissers because they sprad a clear liquid on you .
for us kids , who lived in lane cove , to catch them it was a sin to get them when they came out of their shells and were still wet . we believed if we gave a thousand wings to a certain company , they would give a wheel chair to a poor kid .
since the green grocers had a four - year cycle and the yellow bakers a three - year cycle ever twelve years their emergence would coincide and the din was unbelievable . on off years just a few would come out .
“blue moons” could occur wherever there are “green grocers” with an estimated frquency of 1 / 10000 . but strangely enough , despite the absolute huge numbers of ggs about this 2013 season from september , no blue moons seem to have been found / photographed / handed to the australian museum . claudine’s “indelicate” is probably the nickname given to female cicadas as males croak loudly when caught , females only can excrete water ! chris , what species cam to dive into the pool ?
wow……what a site . last night we had a late night swim in the pool and turned the lights on . big mistake . there were cicadas coming from every here . spent our time rescuing them all . we are in the hawkesbury district . i am over the moon about the number of cicadas . we start them singing by shining a torch in the trees at night . fabulous .
as a child i collected cicadas in sydney . the boys taught me all the names & one of them is not mentioned probably because it is indelicate . it was called the pisswacker presumably because it made no noise and released water on you , it was probably a female and did this when caught .
i am sitting in my mums backyard listening to their song and little else . i remembered the black price also but couldn’t remember the green grocer . thanks for the memory kick is getting much more difficult as i approach my urltoken is mums 86th .
near sydney ( according to l . popple ) . i’ve also read that they are more prevalent in hilly areas .
“my fav one is the blue moon how beautiful . ” how much is it possible ?
excellent page . reminder of the glorious days of summer when i was a youngster . you didn’t mention that the local pharmacist bought black princes wings and made some special concoction from them . why were they known as “locusts” 50 years ago ?
i think they called them locusts because they reminded people of the locusts that are actually grasshoppers .
that ‘chocolate soldier’ one is actually a ‘red rocket’ but i think the names for the other ones are very clever . my fav one is the blue moon how beautiful .

update ( july 2018 ) : a company called meat maniac sells cicadas in a can . don’t know which species , but they have a “nutty flavor” .
also , read this amazing story about how brood vii cicadas helped kept the onondaga nation alive during a time of famine .
[ warning : ] cicadas , 17 - year cicadas at least , are well - known bioaccumulators of mercury . if consuming mercury is a concern , you should not eat cicadas .
dogs , cats , squirrels , fish , and people can’t stop eating cicadas . are they crazy , or “crazy like a fox” ? ( foxes will eat them too . )
people want to know : “is it safe for my pets to eat cicadas” . the truth is in most cases your pets will be fine if they eat a few cicadas , however , you still need to be cautious and keep a close eye on your pets . watch them for odd behavior , and don’t let them gorge themselves . be cautious : the humane society has warned : “cicadas dangerous to pets” [ the original link is gone ] .
pets can choke on the rigid wings and other hard body parts of the cicadas .
pets who consume cicadas sprayed with copious amounts of pesticide can and will die .
bottom line : play it safe , and don’t let your pets eat cicadas if you can help it .
whether they’re curious , hungry , or doing it for the shock value , people are eating cicadas . asian peoples have eaten cicadas for centuries , and there are records o f native americans eating cicadas . people joke that they’re atkins friendly [ also no gluten ] . i’ve heard they taste like asparagus , popcorn , minty shrimp , and piney shrimp — yummy pine .
a man in bloomington indiana had an allergic reaction to cicadas after eating 30 . he was also allergic to seafood — both cicadas and shrimps are arthropods so this makes sense .
you could have an allergic reaction . if you’re allergic to seafood , don’t think about eating them .
stephanie bailey’s internet insect cookbook has tips on how to prepare insects for human consumption ! [ note that the link now goes to an article by stephanie about eating insects in general . ]
bottom line : you’re not a contestant on fear factor [ a reality tv show in the 00s ] . why eat cicadas when you can choose from many of the fine menu choices at applebees [ a chain restaurant ] ?
if a creature has a mouth or some other mechanism to digest cicadas , it likely will try to eat them . cicadas make great fish bait . squirrels ( yes , they’re nuts for cicadas too ) , birds , possums , raccoons , foxes , other insects , fungi… they all love cicadas .
bottom line : let nature do the dirty work and clean your yard one bite at a time .

update ( june 17th ) : i just got back from onondaga county and i can report that the emergence is in full swing . lots of chorusing and mating . the best locations are around the onondaga nation reservation . if you visit , please do not trespass into the reservation — there are plenty of cicadas outside of it . john cooley of urltoken said there are also reports of cicadas in the green lakes state park .
periodical cicadas ( magicicada septendecim , people call them “locusts” ) will emerge in the finger lakes area of new york state in 2018 .
this group of cicadas is called brood vii ( 7 ) and is known as the onondaga brood . this brood is shrinking , and will likely be the next periodical cicada brood to go extinct
what : brood vii is the smallest periodical cicada brood in the u . s . , and is isolated in the finger lakes area of new york state . only one species of cicada belongs to the brood : magicicada septendecim ( click link for sounds , video ) . this cicada has a 17 - year life cycle . sadly , brood vii will likely be the next brood to go extinct .
when : june , but perhaps may if it’s a very warm year . magicicada cicadas typically emerge in the spring , once the soil underground where they live reaches approximately 64 degrees faraihneght .
the following counties have had these cicadas in the distant past : cayuga , livingston , monroe , onondaga , ontario , seneca , steuben , wyoming , york .

the paper was published in vol 4424 , no 1 of zootaxa . link to paper .
in a nutshell : these researchers compared the dna of a variety of cicadas to determine how they are related evolutionarily and how they should be organized in terms of tribes and sub - families .
this is a list of the cicadas found in australia including its outlying islands and territories . the outlying islands covered include : christmas , cocos ( keeling ) , ashmore , torres strait , coral sea , lord howe , norfolk , macquarie , and heard / mcdonald .
the taxonomy followed is from moulds , 1990 . [ 1 ] the genus abricta has since been split . [ 2 ]
the list scope includes outlying islands : 1 . cocos ( keeling ) islands 2 . christmas island 3 . ashmore reef 4 . torres strait islands 5 . lord howe island 6 . norfolk island 7 . macquarie island 8 . heard island and mcdonald islands

casuarina appears to have relatively few insect problems . the twig girdler . . .
cicadas are the loudest insects in the world and there are more than 200 species in australia .
it is thought that the sound produced by some communal species can act as a defence against predatory birds and some are even loud enough ( 120 decibels ) to be painful to the human ear . cicadas also often sing in chorus , which makes it more difficult for a predator to locate an individual .
only male cicadas sing . they do this in an attempt to find a mate .
most of their lives are spent as nymphs underground . for some species this can be up to several years .
birds , bats , spiders , wasps , ants , mantids and tree crickets all prey on cicadas .

the drone of cicadas is one of sydney ' s most recognisable sounds of summer .
they are classified in the order hemiptera , which includes all insects with piercing and sucking mouth - parts . ( other insects in this order are bugs , aphids and scale insects ) . there are more than 200 australian species of cicadas , most of which belong to the one large family , the cicadidae . cicadas are sometimes known as locusts in australia , but that term is more correctly applied to certain migratory species of grasshopper .


arthroschista hilaris , the kadam defoliator , is a moth in the crambidae family .

it was described by walker in 1859 .

it is found in india , sri lanka , burma , cambodia , sumatra , borneo and in australia , where it has been recorded from queensland .

the wingspan is about 30 mm .

the wings are green , the forewings with a brown line along the costa with two brown dots .

the hindwings have brown dots along the margin .

the larvae feed on neolamarckia cadamba .

they have a yellow body with a brown head .

pupation takes place on the ground amongst litter .
