Homalodisca coagulata, the glassy-winged sharpshooter, is an important vector of Pierce's disease and other diseases caused by Xylella fastidiosa. The leafhopper is attacked by several little-known mycopathogens. The attraction of the leafhoppers to feeding conspecifics during host selection appears to benefit the leafhoppers in several ways. These benefits may be offset by exploitation of the behavior by a fungus to spread its infective conidia. Leafhopper behaviors involved in this interaction and their implications will be discussed.
