North American Ecology (US and Canada)
Resident in southwest North America (Scott 1986). Habitats are LOWLAND DESERTS. Host plants are usually herbaceous with most known hosts largely restricted to a few species in one family, Cruciferae
. Eggs are laid on the host plant singly. Individuals overwinter as pupae. There is one flight each year with the approximate flight time MAY1-JUN1 in the northern part of the range and FEB1-APR30 in the southern part of their range (Scott 1986).
