the carolina locust is a large herbivore that can decimate swaths of commercial crops , leaving economic ruin in its wake .
these few observations suggest that the carolina grasshopper is a thrifty feeder because it appears to eat all of whatever it attacks .
two - choice laboratory tests revealed that the carolina grasshopper fed readily on downy brome , smooth brome , western wheatgrass , wheat , barley , dandelion , and kochia . because of its wide distribution , the carolina grasshopper undoubtedly has many more host plants than presently known .

similar dissosteira longipennis usually has more contrasting and obvious spotting over much of body and tegmina , and wings have a clear to pale white margin and base with a bluish tinge at very base . head is proportionately larger . more restricted in distribution ; found on great plains between roughly wyoming & nebraska and new mexico & northern texas ( sometimes straying into bordering regions in high population years ) .
a two - year study was conducted of the california range land grasshopper , dissosteira spurcata saussure . this seldom - dominant i species is not considered of significant economic importance to the agricultural economy of the state , but in proportion to its numbers it coptributes a share of damage to range land forage , it has only been since the advent of the chlorinated hydrocarbon insecticides that a true appreciation of the damage potentialities of range land species has been realized .
because of its large size the carolina grasshopper has been regarded as a voracious feeder capable of causing much damage at moderate densities . the live weight of males averages 570 mg and of females 1 , 467 mg ( dry weight : males 171 mg , females 387 mg ) .

a male carolina grasshopper with mite infestation in allegany co . , maryland ( 7 / 12 / 2012 ) . per richard ,
the red blobs are the parasitengone larvae of erythraeid mites ( family erythraeidae ) . if you enlarge the photograph you can see that the mites are attached along the wing veins and are engorging themselves on the blood of the grasshopper . once full the mites will drop off the grasshopper much as an engorged tick would on a human . the grasshopper was paying a price for being infested with these mites - - it was only about 2 / 3rds the size of a normal carolina grasshopper .

, that makes an animal difficult to see . an animal can do this by having a coloration similar to the background , as with the carolina locust , breaking up its outline , countershading ( fish have dark backs , light bellies ) , or one of the coolest , changing colors , like our native gray treefrog ( or is it green ? ) .
the carolina grasshopper , a ground - dwelling species , is active chiefly during daylight hours . emerging from overnight shelters , both nymphs and adults bask in the morning sun for two to three hours beginning approximately two hours after sunrise . they turn a side perpendicular to the rays and lower the associated hindleg to expose the abdomen , and they often appress the flexed hindleg close against the ground .
the adults appear during may in new mexico and eastern nebraska , during early july in eastern wyoming , and during late july in western idaho . once carolina grasshoppers acquire functional wings , they fly and disperse extensively . adults may move distances of several miles or more , as they have been found in the center of large cities . the full extent of individual dispersal , however , is unknown .
the main characteristic of band - winged grasshoppers is that the hind wings are usually brightly coloured ( figure 8 ) . while in flight , these grasshoppers may produce a cracking sound with their wings . the carolina grasshopper with its black wings fringed with a pale border is probably the most noticed member of the group ( figure 9 ) . the most economically important species is the clear - winged grasshopper .
several observations of the carolina grasshopper ' s feeding in nature have been made . on 5 august 1992 at 6 : 51 p . m . dst with soil temperature 81°f and air at 1 - inch level 74°f , an instar iii female climbed a 3 - inch tall kochia plant and in a vertical head - up position fed on a kochia leaf ( 2 x 7 mm ) beginning at the tip and devouring it to its base leaving a 2 mm stub .
each shed of the exoskeleton ( called an instar ) brings the nymph closer to sexual maturity . with carolina locusts , they get larger and darker . the females will get larger than males ( about 2 . 5
long ) . despite the color changes , at each stage they are nearly perfect at blending in to their background . perhaps the color change from nymph to adulthood forces them to find new backdrops with which to camouflage and avoid competing with other life stages in this way .
the carolina grasshopper is a strong , adept flier . during warm , sunny days the adults frequently fly over bare ground interacting with one another . males are noted for their hovering flight . they rise almost vertically from the ground to heights of 3 to 6 feet , occasionally higher , and hover for 8 to 15 seconds . at the end they flutter down to the ground close to where they started . they may repeat this maneuver as many as five times . during the hovering flight they produce a soft , sibilant sound . the hovering behavior may be a part of courtship in that it attracts females . the display also attracts males so that a small aggregation of several males and a female may gather on the bare ground beneath the hovering male .
the nymphs emerge over a period of at least two weeks and develop in a habitat of grass and weeds with much interspersed bare ground . hatching , however , may at certain times and places be extended over several weeks so that as many as four different instars ( i to iv ) coexist together in a habitat . limited data obtained in eastern wyoming indicate a nymphal period of 40 days at an altitude of 4 , 700 feet and 55 days at an altitude of 6 , 100 feet . reared in the laboratory , nymphs complete development in 52 days at a constant temperature of 77°f and 26 days at a constant temperature of 86°f . the carolina grasshopper has been described as a heat - loving species that prefers the hot , bare areas of its habitat .

acridium ( oedipoda ) carolinum ( linneaus ) s . h . scudder , 1901
appears butterfly - like in flight . males ( mostly ) crepitate faintly in flight , and stridulate ( sing ) by rubbing hind legs on tegmina .
often confused with mourning cloak butterflies ( nymphalis antiopa ) due to similar size and wing coloring , but body shape and behavior is quite different , so any confusion should be short - lasting .
most of lower 48 united states except southern florida , gulf coastal plain , southwest arizona , and bottom 2 / 3rds of california .
often mistaken for a butterfly due to large size and often rather lazy bobbing flight . probably the bandwing grasshopper most familiar to the most people in north america , due to it ' s preference for disturbed often dusty habitats , such as dirt roads , paths , vacant lots , etc .

on 27 july 1990 at 9 : 10 a . m . an adult male was discovered sitting on ground litter facing the sun in a city lot . at 9 : 13 a . m . the male began to stir and walked a short distance to a short grass , buchloe dactyloides . at 9 : 14 a . m . the male reached up with its mouthparts to the tip of a leaf and consumed the whole leaf to the base . he then attacked another leaf of the same plant , cutting it near the middle . holding onto the cut section with the front tarsi , he consumed all of it from the cut end to the tip . he then cut another leaf of the same plant near the base , held onto it with the front tarsi , and ate all of it . a fourth and final leaf was eaten from the tip to the base . feeding ended at 9 : 24 a . m . during all of the feeding the male sat horizontally on the ground , resting on the mid - and hindlegs and using the forelegs to handle the food . the weather was clear , warm , and calm ( soil surface 94°f , air 72°f , at 1 - inch level , wind 0 - 2 mph ) .
on 2 october 1992 from 4 : 28 to 4 : 37 p . m . dst ( soil surface 92°f and air 1 - inch level 80°f ) , three females wandering around on bare ground were observed to feed on ground litter ( dry grass and unidentifiable vegetation ) . the females were horizontal on the surface . one female was observed to spread out her front legs rather than use the front tarsi to handle the food .
in voluntary or appetitive flights , adults fly a distance of 2 to 36 feet at heights of usually 1 to 2 feet . they undulate and may crepitate as they fly . adults are wary and flush readily at the approach of a person . in flushed flight they may travel a distance of 4 to 70 feet or much farther in a strong wind . they fly at heights of 1 to 5 feet and often make a right angle turn at variable distances into the flight before landing on the ground .
no special study of dispersal or migratory flight has been made , but it is known that adults have moved from resident localities near boulder , colorado to nonresident mountain sites above 10 , 000 feet , approximately 14 miles west . in the vicinity of washington , d . c . , considerable numbers frequently fly around the electric lights during warm summer nights . the species has also been collected at lights in presidio , texas and in north branch and minneapolis , minnesota .
) . the wingspread of the males measures 3 inches and that of the females 3 1 / 2 to 4 inches . the hind wings are black with a pale yellow margin (
) . the tegmina are colored tan , brown , or gray matching the general body color and are faintly speckled .
1 . head with face nearly vertical ; antennae filiform , terminal segments dark , basal segments colored like body ; lateral foveolae small and triangular .
) ; hind tibia of instar i and ii black with basal annulus pale yellow , hind tibia of instars iii to v with variable patterns of tan , gray , and black ; hind tarsus white or pale yellow except distal end fuscous .
4 . general body color tan , brown , or gray . reddish in individuals developing on red soils .
sexual maturation of females appears to be prolonged . in minnesota , where the adult stage is reached in early june , the females do not begin to oviposit until early august , suggesting that nine weeks are required for maturation . in manitoba , oviposition has been observed in september and in wyoming in september and october .
the female selects compact bare ground exposed to the sun in which to oviposit . the selected site is often the edge of a gravel or dirt road . she works her ovipositor to a depth of 1 1 / 2 inches and deposits a large clutch of eggs that she encloses in a sharply curved pod (
) . after approximately 1 1 / 3 hours , she extracts her ovipositor and for one to three minutes brushes surface particles with her hind tarsi over the aperture of the hole . the pod , nearly 2 inches long , usually contains more than 40 eggs . two egg pods obtained after observing the females oviposit at the edge of a gravel road in southeastern wyoming contained 50 and 57 eggs , respectively . reared in a greenhouse , caged females have laid from 30 to as many as 70 eggs in a pod . the eggs are reddish brown and 4 . 8 to 5 . 8 mm long .
although adults are conspicuous because of their size and flashy wings , giving the impression of large numbers , the density of populations is usually low , around 0 . 1 to 0 . 2 young adults per square yard . populations irrupt infrequently , as in southern saskatchewan in 1933 and 1934 , causing serious loss of crops . no estimates of absolute densities were determined during this outbreak .
after basking , the adults begin to walk and fly about the habitat . the males are more active than the females , perhaps searching for receptive females with which to mate . females walk and fly far less than males , but do more feeding , grooming , and resting . seven observations of feeding by adults indicate that this activity occurs in the afternoon from approximately noon to 5 p . m . dst . an observation of courting occurred at 12 : 25 p . m . mating pairs have been observed in the afternoon : two pairs at 2 : 15 p . m . , one pair at 3 : 15 p . m . , and one pair at 3 : 47 p . m . in the george reserve , michigan , a pair observed in copulo at 5 : 20 p . m . on august 4 , remained together until 7 : 50 a . m . the next morning . three extended observations of oviposition in eastern wyoming indicate that females perform this function during midday with oviposition beginning as early as 10 : 30 a . m . and as late as 2 : 30 p . m .
hot ground temperatures of 110°f . and air temperature of 90°f . , 1 - inch level , induce the adults to stilt . as temperatures rise , the grasshoppers climb on vegetation and place themselves 1 - 3 inches above ground . they face the sun directly so that only the front of the head is exposed to the rays and the rest of the body is shaded .
in the afternoon the adults bask on bare ground for a second time beginning about 3 p . m . and ending about 5 p . m . then they walk or fly to vegetated areas where they seek shelter usually under canopies of grasses . sampling of their density on a bare , gravel road in laramie county , wyoming on 4 october 1992 showed that adults ( 0 . 06 per square yard ) were 20 times more prevalent at 4 p . m . dst than at 5 : 17 p . m . , and none were found at 5 : 29 p . m .

) . it seems like any dry lot or gravely path has at least a couple of these every 10 feet or so that will just explode off the ground when you get close enough . while at rest they virtually disappear into the background - unless that background is a blue tarp - but when they fly , their black wings with yellow border stand out ( in flight they superficially resemble mourning cloaks ) .
) , they have three stages ( egg , nymph , adult ) . note the different terminology - larva is for animals with complete metamorphosis , nymph for animals with incomplete metamorphosis .
having distinct life stages allows for a species to partition up habitat between life stages ( e . g . monarch caterpillars eat foliage , adults eat nectar ) rather than compete for resources . because nymphs strongly resemble adults ( except having underdeveloped wings and no reproductive organs ) , they might compete for resources . dragonflies and many other insects avoid this by having aquatic nymphs and terrestrial adults . we can add a new term here :


the quokka ( / ˈkwɒkə / , setonix brachyurus ) , the only member of the genus setonix , is a small macropod about the size of a domestic cat .

like other marsupials in the macropod family ( such as kangaroos and wallabies ) , the quokka is herbivorous and mainly nocturnal .

quokkas are found on some smaller islands off the coast of western australia , rottnest island just off perth and bald island near albany and in isolated scattered populations in forest and coastal heath between perth and albany .

a small colony exists at the eastern limit of their range in a protected area of two peoples bay nature reserve , where they co-exist with the critically endangered gilbert 's potoroo .

.
somehow , a quokka has managed to escape rottnest island by boat and is now scampering somewhere around the canning vale area .
the word ' quokka ' originates from the language of nyungar ( noongar ) people , who were aborigines of the area .
quokkas on the remote offshore islands of rottnest island and bald island are strictly protected and the quokka populations there are stable .
the detection of a baby quokka has sparked hope the fragile population decimated by the devastating northcliffe bushfires in 2015 is recovering .
quokka cruelty comes in various forms and is regrettably a recurring problem for the quokkas on rottnest . a police cracked down on acts of violence leading the injury and death of nine quokkas on rottnest island in 1998 lead to greater supervision of school leavers who , at that time , considered kicking a quokka a “rite of passage” . yet quokka cruelty did not cease to occur . in january 2003 , it was reported that the ‘game’ of ‘quokka soccer’ resulted in the brutal death of eight resident quokkas on rottnest island . quokka hockey was the next “cruel craze” to follow and greater fines for acts of animal cruelty perpetrated against quokkas ensued . sadly , quokka cruelty continues . in february 2015 , five quokkas were found dead having been “stuffed head - first into tree protectors” on the island . there have been additional cases of extreme quokka cruelty . for example , in april 2015 two french tourists were caught and fined $ 4000 each for attempting to set a quokka on fire using a deodorant can and a lighter . in december 2015 , a man was charged $ 2500 for kicking a quokka who was sitting peacefully on a rottnest island road .
perhaps the most disturbing of our quokka facts has to do with their maternal instincts . many other animals will fight , and even die , for their children , but not so with quokka mothers . when threatened , quokka mothers pull their joeys out of their pouches and throw them on the ground , where they’ll squeal . the sound attracts the predators , who then eat the babies , giving the mothers time to get away . as far as quokka mothers are concerned , they can always have another child .

quokkas have a symbiotic relationship of parasitism , like mundulla yellow . the mundulla yellow is a fatal disease to animals . if the quokka eats the mundulla yellow , it could die . another one is a commercialism , like shrubs . the quokka sleeps in the shurbs and it protects them from predators . a squirrel is another example because the squirrel can also use the paths the quokka makes .
one of the men ignited an aerosol spray with a lighter and singed the quokka while the other recorded it on his mobile phone .

being a macropod the quokka has all the familiar characteristics as these types of animals . it has short small forelimbs with hands with five clawed fingers for grasping and pulling down branches , fighting and grooming . its hind legs , which are relatively short compared with other macropods , are used for hopping . while very efficient at speed , the quokka ' s hind legs are ineffective at low speeds and hardly used . it uses pentapedaling locomotion at slow speeds . the female quokka raises its offspring in a pouch located on its abdomen . male quokkas don ' t have pouches . the male quokka is larger than the female . a quokka weighs between 2 . 5 to 5 kilos and is between 40 to 54 centimetres in length .
the quokka ' s habitat is a dense vegetation and it lives close to water . the quokka lives in a large grassy land also known as a grassland . the quokka ' s niche is very narrow due to the fact that is being preyed on by many other animals . it ' s role in the environment is to be a prey for other animals to feast off of . the quokka is endangered because the wetlands are disappearing and they are getting introduced by humans and it makes for easy prey for other animals . they prey on grass , leaves , and other fruits .

in the northern jarrah forest the quokka is restricted to agonis swamp shrubland habitats that form in the open , upper reaches of creek systems . this restriction was probably initially due to the high water requirements of the quokka , but is likely to have been exacerbated by increased predation since the arrival of the fox ( hayward 2002 ) .

while the ria had been unable to draw a direct link between the internet trend and tourist numbers , it suspects the quokka has become the island ' s biggest drawcard .
as a species which depends on a complex forest structure , the quokka is susceptible to the indirect impacts of the phythophthera plant pathogen due to death of vegetation where the species occurs ( dec 2013 ) . the loss of forest structure has the potential to increase the risk of predation of and loss of resources for the quokka ( dec 2013 ) .

ms knight said .
not all humans are nice to quokkas . occasionally you hear of incomprehensible cruelty by humans towards these harmless animals . in april 2015 two french tourists ignited an aerosol spray producing a 30cm flame that singed the fur on the head and body of a quokka . they were each fined $ 4 , 000 and jailed when they claimed they couldn ' t pay the fine . the quokka survived the ordeal without serious injury and was spotted on the island with burnt fur on one side of its body . in february 2017 a man was videoed kicking a quokka numerous times . he was fined $ 4 , 000 . a new zealand man caught a quokka and threw it into the sea . luckily the distressed animal swam ashore safely . the man claimed in court that he merely “placed” the quokka in the water and that he didn’t actually throw it in . the judge fined him $ 2 , 000 for his act of cruelty .
it is believed that since european settlement , the quokka has been lost from more than half of its former habitat range in mainland wa , and it is now considered a threatened species .
the overall objective of the draft recovery plan ( dec 2013 ) is the retention of the current distribution and abundance of the quokka . the broad recovery actions identified in the plan are :

both men were initially charged with cruelty to an animal , but the charge was downgraded after prosecutors said the quokka was not able to be found , to determine its condition after the attack .
according to a research , quokka is capable of bearing high temperatures of up to 44°c ( 4 ) due to its thermoregulatory abilities . however , the possibility of dehydration is not ruled out .
until recently , many people outside of australia had never heard of the quokka , a muppet - cute ( despite its beady eyes and rat ' s tail ) marsupial with an irresistible smile .
use a popular internet search engine to type in ‘quokka’ and you will discover a plethora of stories about a species of small marsupial inhabiting rottnest island ( wadjemup ) , situated approximately 18 kilometres from perth , western australia . these stories , at present , comprise an even split between the quokka selfie trend , with ‘selfie’ images being shared by the likes of celebrities such as hugh jackman ( type ‘quokka selfie’ to view images and prepare to be astonished at the sheer volume of results ! ) , and news stories about horrific acts of wanton cruelty perpetrated against these friendly , furry animals .

feral pigs ( sus scrofa ) destroy swamp and riverine habitat of the quokka and compete with the species for resources . feral pigs also disturb the dense riverine vegetation , opening it up and allowing predators into otherwise inaccessible areas ( dec 2007 ) . there have been anecdotal reports of areas , which previously supported quokka populations , becoming unsuitable due to disturbance by the feral pig ( dec 2013 ) .

marketing experts and scientists will come together on thursday for the island ' s first - ever quokka symposium , to discuss ways to harness the online popularity of the marsupial to boost tourism and conservation .
oddly , the quokka can thank criminals for its abundance on rottnest : late 1830s legislation designated the island an aboriginal penal colony , which kept most everyone else away ( thus leaving habitat intact ) .
journalist kenneth cook learned the hard way when he tried to befriend a quokka along a dirt road . cook noted the animal’s “small , mean mouth , ” but decided it was probably too small to do much damage . “it was a malicious - looking beast , ” he wrote in his 1987 book wombat revenge , but he wasn’t afraid . he offered the little animal a piece of apple , which the quokka spat out , and a crumb of gorgonzola cheese . the quokka popped the gorgonzola into its mouth , chewed , and then , cook says , “fell down in a dead faint . ”
the quokka , setonix brachyurus , was described by early dutch explorer , willem de vlamingh , ' as a kind of rat as big as a common cat ' . his first sighting of the quokka was on an island off the mouth of the swan river . he named the island rottenest ( ' rat nest ' ) in honour of this sighting . the island is now known as rottnest island .
convinced he’d just poisoned the creature and determined to save it , cook zipped the quokka’s body into his backpack , left a little room for air , swung the pack onto his back , and pedaled his bicycle frantically down the road to find help . after a few minutes of bumping along at breakneck speed , the quokka began to revive , and blearily climbed out of the backpack , claws first .
the name
quokka
comes from the name given to the animal by the aboriginal people living in the augusta and king george sound area of the south - west of western australia . a marsupial the size of a hare or domestic cat , the quokka is the sole representative of the genus setonix . as with other marsupials , such as the kangaroo , wallaby , wallaroo , bettong and potoroo , the females suckle their young in a pouch . they give birth in late summer , after a gestation period of twenty - seven days , and the young quokka remains in the pouch until august or september , and is then suckled for a further two months . the quokka reaches maturity at about one - and - a - half to two years of age , and lives to be ten years old .

quokkas on rottnest island exhibit a capacity to rapidly respond to habitat changes arising after fire . a major fire on the island in 1956 altered the vegetation composition and structure ( pen and green 1983 ) , which was exacerbated by overgrazing by quokkas ( storr 1963 ) . despite this , the quokka population has increased ( pen and green 1983 ) . clearly , the quokka is able to cope with habitat change .
although many species with formerly continuous distributions are being turned into metapopulations by habitat fragmentation ( hanski and gilpin 1991 ) , this is not the case for the quokka , which existed in naturally fragmented habitats . virtually all historical reports ( gould 1863 ; white 1952 ) link the quokka to areas of dense vegetation ( either swamps and thickets in forest or coastal shrublands ) , and these discreet patches provided habitat for populations within a greater meta - population ( hayward et al . 2003 ) . the quokka is increasingly restricted to such discreet habitat patches because dispersal between patches no longer occurs ( hayward et al . 2003 ) .
the word ' quokka ' is pronounced in a number of different ways . some pronounce it kwo - ka ( rhymes with “mocha” ) . the majority say kwah - ka ( rhymes with “wokka

it is important to remember that the quokka may not be restricted to densely vegetated areas on the mainland ( christensen et al . 1985 ) because these areas are most favorable to it ; rather , they may be the habitat least “favored” by the apparent agent of the quokka ' s decline ( caughley and gunn 1996 ) , the red fox . in this case , the swamps are probably acting as a refuge for quokkas from fox predation .
a quokka is roughly the size of a domestic cat . it has a roundish face and head with short rounded teddy - bear ears , black nose and black eyes . the quokka is best known for the shape of its mouth , which gives it a cute mona - lisa smile that has made it the darling of selfie photographers . it is a herbivorous marsupial macropod and belongs to the same family of animals as the kangaroo and wallaby .

we’ve all seen the photos that made the rounds last year : a furry little critter beams at the camera , at a leaf , at a tourist . from this adorable gallery —which naturally went viral—we can discern two facts : 1 ) that the furry little critter is called a “quokka” ; and 2 ) that this quokka , whatever that is , must be the world’s happiest animal . it even says so , right there in the photo gallery .
is solely comprised of the surrounding plant material . the quokka most commonly feeds on different grasses that line that tunnels that they make through the dense vegetation . they are also known to eat leaves , and fruits and berries when they are available . although the quokka mainly browses for food on the ground , they are also known to climb about a meter or so up into the trees , and also swallow their food without chewing it . the quokka then regurgitates the undigested material in the form of a cud , which is also eaten . they have no need to drink vast amounts of water and are said to be able to go for months without drinking at all .

clearing of dense vegetation has contributed to the quokka ' s decline because it progressively fragments the habitat . this increases the distance between suitable swamp habitats , and increases exposure to predators . habitat clearing is attributable to agricultural developments ( grazing and cropping ) , urbanisation , and logging . it has been noted that approximately 60 % of quokka records are within state forests or timber reserves , which are likely to be harvested in the future ( dec 2013 ) .

the quokka bounds and hops along the ground although it can climb trees if it needs to . it will sit on its hind legs to look around and will also use its front paws to search for and pick up food .
breeding in quokka populations occurs from january through to march . it takes 27 days for a single joey to be born . once it is born it crawls along the mother’s fur up to the pouch and attaches to a teat .
historically , the quokka had population traits of a
classic metapopulation
( spatially separated populations with occasional inter - population migration ) . traits include restriction to discrete habitat patches , occasional inter - patch movement , lack of correlation between the dynamics of each population , and reports of frequent localised extinctions and colonisations . the massive decline of the quokka in the 1930s has resulted in populations that are the remnants of this original metapopulation ( hayward et al . 2003 ) .

the quokka is a small marsupial that lives mostly along the coast of western australia in a tropical grassland biome . they usually live in small family groups . their natural predators are mainly humans , who have been decreasing the population of quokkas since australia was first discovered . however , they are also hunted by birds of prey such as hawks and eagles . sadly , the quokka ' s numbers are continually decreasing , mostly because of human interaction . they are now considered vulnerable .
once abundant across australia , the arrival of the dingo more than 3 , 000 years ago , followed by foxes in the late 1800s , saw quokka numbers dwindle on the mainland . today , the quokka population is restricted to the south - west region of western australia , most notably off perth on rottnest island . the island gained its name from these adorable creatures in the 1600s , with dutch navigator williem de vlamingh describing the quokka as “a kind of rat as big as a common cat” and calling the island ‘rotte nest’ , meaning ‘rat’s nest’ . mainland populations are found around dense streamside vegetation , shrubland , and heath around swamps . they live in a wide range of semi - arid areas on rottnest island .
the specific habitat preferences of quokkas may have evolved to enable them to cope with the frequent , low - intensity fire regimes implemented by australian aborigines ( ward and sneeuwjagt 1999 ) . aborigines used fire to hunt the quokka by burning the swamp and spearing animals as they fled the flames ( gardner 1957 ; gould 1863 ) . however , whether aborigines burned the swamps at a frequency that coincided with peaks in quokka abundance or whether quokka abundance peaked in accordance with the aboriginal hunting regimes is unknown . directly igniting the swamp contrasts with modern - day low - intensity control burns that generally burn the swamp edges without penetrating the swamp . this leads to a reduction in swamp vegetation without creating a mosaic of seral stages .
in response to repeated acts of quokka cruelty , financial penalties are being imposed on individuals convicted of harming or killing quokkas ( although i dread to think how many abusers are not caught ) . we could , in my opinion , do more to protect these vulnerable marsupials . firstly , the maximum penalty allowed under the law needs to be imposed to punish those who wantonly torture and kill quokkas ( and all other nonhuman animals for that matter ) . since the maximum penalty for harming a quokka is currently $ 50 , 000 ( new legislation could see the penalty raised to $ 300 , 000 ) , it seems largely ineffectual as a deterrent to others when convicted quokka abusers are only fined a few thousand dollars .

mating can take place at any time of the year in quokka populations . due to predation and other factors they generally only have one each year so they can focus on protecting that one . in zoos they can breed all year round .
