Unknown in Alberta. Larvae are light brown with a number of darker and lighter longitudinal lines and have two short 'tails' (Scott 1986). Adults do not stray far from their natal grounds, and live 5-11 days on average depending on weather conditions (Scott 1986). Males perch in the morning on small hilltops to await passing females. The short, rapid flight caused Scott (1986) to call this the Grasshopper Satyr.
Conservation
Restricted Canadian range; Ranked "Sensitive" in Alberta, possibly extirpated in Manitoba.
Diet Info
Unknown in Alberta. Blue Grama Grass (Bouteloa gracilis) is a host in the US. Adults occasionally nectar at yellow composites (Scott 1986).
Range
Southern Alberta and Saskatchewan south to New Mexico (Scott 1986). Previously also occurred in Manitoba, where it appears to be extirpated (Layberry et al. 1998).
