North American Ecology (US and Canada)
Ancyloxypha numitor is resident throughout the eastern United States and southeastern Canada (Scott 1986). Habitats are subtropical to lower Canadian zone moist grassy places and streamsides. Host plants are multiple species of grasses. Eggs are laid on broad-leaved grasses singly. Individuals overwinter as third and fourth instar larvae. There are several flights each year with the approximate flight time June 15-early July and Aug. 1-early Sept in the northern part of their range, and multiple flights between Feb. 1 - Dec. 31 in the most southern part of their range (Scott 1986).
