scatological costume may fool a bunch of PhD, but do the predatory wasp 1 for fooled to find out. The researchers used spectrometer to confirm the spider in the web is especial inextinguishable from bird's bread. Then they changed the the covering of some webs by dusting them with carbon powder,and they found that spiders that rest on the artificially black and silk were much more likely to get eaten. Now this result don't prove that wasps buy the whole put ,maybe spider against the white background are just harder to spot, to be more confident that looking like poops is key,researchers may test the wasps to found out if they are just glimpse it and stepping it.
