Lichen Katydid - Markia hystrix
Katydids comprise a diverse group of insects particularly well adapted to survival in rainforest because of their exceptional camouflage. Most katydids are well camouflaged with brown or leaflike green markings.
The Lichen Katydid, Markia hystrix (Orthoptera - Tettigoniidae), however, has one of the most incredible camouflages of all. It resembles the pale greenish-white lichens on which it lives in rainforest treetops. Not only does the color match the lichens, but the body and legs have a bizarre assortment of spines and points that blend well with lichens, in fact, so well that this insect is extremely difficult for predator to find.
This astonishing insect is known to occur in Central America (Costa Rica, Panama), Colombia and Ecuador.
