Abstract

Variation in the insect body plan Treehoppers are close relatives of cicadas that have a bizarre and varied structure called the 'helmet' growing from the wingless first thoracic segment. The helmet is classically described as a cuticular expansion of the first thoracic segment. Closer examination now shows that, in evolutionary terms, it corresponds to a third pair of wings. A striking feature of body plans is their relative stability over long evolutionary times. The discovery of this previously unknown variation of the blueprint for insects illustrates how a structure relieved of its original role is free to evolve new functions and morphologies.
