Argynnis coronis hennei

'Henne's' Coronis Fritillary

Argynnis coronis hennei is not widespread; it flies at Mt. Piños, Frazier Park/Mountain, Mt. Abel, and the Tehachapis, according to Ken Davenport. It's easily confused (by me) with the more common Argynnis callippe macaria, with which it flies much of the time on Mt. Piños, the only place I know it from. It does, however, fly later: from June into September, while the flight of callippe macaria usually begins in late May and ends in July. So in August-September, coronis hennei may still be flying, while seeing callippe macaria after August 3rd would be a late record (last time I checked).
