Individuals overwinter as larvae or pupae. There is one flight each year with the approximate flight time JULY1-AUG30 in most of the range, JUN15-JULY15 in lower altitudes, and JULY 15-AUG15 in the most northern parts of the range (Scott 1986). Synonomized with Plebejus glandon by some sources (Scott 1986).
