scientific name    Neominois ridingsii    

common name     Ridings' Satyr

Dry, sparsely vegetated prairie grasslands.

The singly yearly brood flies from mid June to early July.

Sandy, greyish-brown with a broad, irregular tan-white submarginal band. Two forewing eyespots. The underside is most similar to Oeneis alberta, but the contrasty, grey-brown and white upperside of ridingsii is unique. Subspecies minimus occurs in Alberta.

life history
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.

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).

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).
