Host plants are grasses, including Stipa and Poa pratensis. Individuals overwinter as larvae. There is a variable number of flights based on latitude, with one flight in the northern part of the range and in the Rockies, with approximate flight time July15-Aug. 15 and multiple flights in the southern part of their range, with the approximate flight times Mar. 31-Oct. 31 (Scott 1986).
