Choeradodis
Choeradodis is a genus of praying mantises with common names such as shield mantis, hood mantis, and leaf mantis because of their extended, leaf-like thoraces. The distinguishing characteristic of Choreododis from which it takes its common names is a laterally expanded thorax. This adaptation for the purpose of camouflage, as well as a rounded wing case and a habit of staying relatively flattened, aid its leaf mimicry. Tiny liverworts, lichens and fungi have been found growing on the pronotum and wing case of many Choeradodis mantids; these appear to be opportunistic growths rather than an example of coevolution with the mantids to afford extra camouflage.
