The glassy-winged sharpshooter, Homalodisca coagulata (Say), is found throughout southeastern US and regions of California. It is thought to have 2 distinct generations per season. Adults over winter in a reproductive diapause that can be induced with a photoperiod of 13:10 L:D. In north Florida, this photoperiod occurs in early August. We propose that this relatively early reproductive diapause is a life-history response to predation pressure by Gonatocerus spp. egg parasitoids.
