Stick insects keep evolving to have the same strange body plans over and over again, scientists have discovered. This evolutionary blueprint has enabled researchers to predict the critters' next ...

Stick bugs are a fascinating insect variety. They have uniquely camouflaged bodies that make them fun models in science education. But their eating habits can devastate trees and damage forests.

A team of biologists in Montana and Germany has found that, regardless of type, those insects that express a protective stick- or leaf-like appearance all evolved the same basic body parts.
