Cercopoda

Cercopoda are the short style-like processes of which there are a pair at the hinder end of some insects, such as cockroaches, grasshoppers, etc. They are regarded as the rudiments of a pair of limbs, and are thus of interest, as they are the only legs in insects which are not on the thorax or middle division of the body. They apparently suggest that the ancestral form of the insects had a pair of legs to each segment of the body.
