North American Ecology (US and Canada)
Asterocampa celtis is a year-round residen in the southwestern United States, and ranges into s. Mex. (Scott 1986). Habitats are subtropical to transition zone wooded areas. Host plants are trees including several species in one genus, Celtis (Ulmaceae). Eggs are laid on the host plant singly or sometimes in groups of several to 20 eggs per cluster. Individuals overwinter as third-stage larvae. There are multiple flights each year in the southern part of their range (s. Tex and Fla.) approximate flight times Mar.1-Nov 30; three flights in Mo; and about 2 flights in the northern portion of their range (June1-Sept30) (Scott 1986).
