Open woodlands and parkland.

Flies primarily in July and August, peaking in late July.

Forewing pale grey with fine dark striations and usually weakly developed costal wedges; Black AM and PM lines variably developed, median line usually absent. Black discal spot. Hindwing slightly paler, sometimes with PM and submarginal line and discal spot. Terminal line finely checkered black and white. Sexes similar.
