In the animal kingdom , sometimes the good survival strategy is to dissemble to be something you ’re not — either to ambuscade unsuspicious prey or to convert predators that you ’re not very tasty .
And scientist recently discovereda spiderthat uses a unequalled masquerade to obliterate in apparent sight . It is the only bonk wanderer to have a body that digest an uncanny resemblance to a dangling , partially dried - up foliage .
A newfound and rare spider species found in China is the only spider that masquerades as a leaf.
The breakthrough was report in a new subject area , though the spider is yet to be described and assigned a species name .
The newfound costume arachnid is in thePoltysgenus in the orb spider kinsfolk , which check more than 3,000 species and one wanderer celebrity from tyke ’s fiction — aAraneus cavaticuswas the barn wanderer Charlotte from the definitive story " Charlotte ’s Web " ( Harper and Brothers , 1952 ) .

A leggy masquerade ball?
Masquerading is far more vulgar in insects than in arachnids . In fact , many types of insects have body that mimic plants . For model , the Phasmatodea order check century of metal money of so - calledstick insects , which look like stripped branches or leafage . And brightly colored orchid mantid have petal - shaped legs to nail their camouflage as harmless flower , tricking other insects into pilot close enough for the mantis to snatch them out of the air .
But about 100 spider species also sport forcible features that make them appear nonliving and unappetizing , like a jumble of twigs , plant detritus or a mussy globof Bronx cheer poo .
This is the first known wanderer species to be leaf - shaped . And its discovery was accidental , according to the report ’s lead writer , Matjaz Kuntner , a principal investigator with the Evolutionary Zoology Lab at the Biological Institute Jovan Hadzi , Scientific Research Centre of the Slovenian Academy of Sciences and Arts .
The greenish-yellow underside of the spider resembles a fresh leaf, and the hairy, stalk-like structure curving from its abdomen makes it look even more like a plant.
Make like a leaf
The scientists spied and photographed the unusual arachnoid in 2011 , while looking for other types of spider in Yunnan , China . They found the individual — a female person — on a sprig , surround by dead leaves and with no web nearby . The researchers remark that her back looked like a living , green folio , while the underside of her body was brown , mimicking a dead foliage , and a hirsute , stalk - alike social organization protruded from her abdomen .
leave close by the distaff wanderer on the arm were attachedwith silk , which hinted that she had place them there purposely to further camouflage herself . However , additional reflexion would be necessary to confirm this behaviour , Kuntner told Live Science .
After searching for two weeks , Kuntner and colleague were able-bodied to come up only one moreleaf - shapedspider — a juvenile male person , crouching on a World Wide Web . Next , they turn to museums to see if they could rick up more specimen , Kuntner say .
" Having first noticed their oddity in nature , we talked to conservator and established their overall curio , " he said . One similar specimen eventually emerged from a museum collection — a female that had been found in Vietnam . But the scientist suspected the Vietnam wanderer go to a known species in thePoltysgenus , whereas the other two spiders belike representeda new species .
There is still much to be read about this enigmatic folio imitator — and considering how difficult it was to retrieve just the first two representatives , that ’s easier said than done . The writer concluded their survey with the somewhat rueful observance that the mysterious spider ’s secretive habits and nocturnal lifestyle enabled it to successfully forfend not only predator , but researcher as well .
The finding were published online Nov. 11 in theJournal of Arachnology .
