Studies were conducted to characterize the occurrence of the greenbug holocycle at research sites that were established in a north-south transect ranging from South Dakota to Texas. Sexual morph production began in mid to late October and peaked in November. Oviposition began in November and ceased in December. Greenbugs were capable of producing oviparae and viable eggs throughout the primary hard red winter wheat production area of the Great Plains. Failure of greenbug sexual reproduction appeared to be related to local climatic conditions.
