Some others look so much like a leaf, that when they are in the natural resting place, they are virtually impossible to see. That is why they are collected at night when they are active and away from the daytime "hiding" place. Not only do the wings look like a leaf, but the legs look like twigs! This one is known as Orthoptera Tettigoniidae Pseudophyllinae Typophyllum mortuifolium.
Some katydids take camouflage to the extreme by mimicking other types of insects. It only makes sense that if you look like a wasp and walk like a wasp, that you must sting like a wasp. Not true for this master of disguise! It is another katydid known to scientists as Orthoptera Tettigoniidae Phaneropterinae Aganacris sp.
This is a lichen mimic katydid (Orthoptera Tettigoniidae Pseudophyllinae Championica sp.) of an as yet unidentified species. It uses its coloration to blend in and disappear in the lichen covered trunks and branches of the rain forest. Many of its predators are visually oriented, such as birds and moneys. In addition, it is covered with hard spines which would deter any predator that may find it by the sound of its "song", such as bats.
Some of the Katydids discovered in Peru during research conducted with Dr. David Nickle
and Dr. Jim Castner.
