Description

A small tailless butterfly with a wingspan of 2.5-3 cm (1-1.5 in). The distinctive upper side of the wings is orange with a wide black border. The underside of the wings are greyish-brown with rows of black spots bordered by white. Caterpillars are 10 to 15 mm long and are green with a white line down the back.

Adults fly from early June to mid-July. Found only in the Okanagan Valley wherever Antelope-brush is present in close proximity to wildflowers including Yarrow, Gray Horsebrush, Brown-eyed Susans and Buckwheats. Eggs are laid solely on Antelop-brushe
Sparse cover of Ponderosa Pine and the presence of wet puddling sites may be important features.
