Oeneis uhleri is resident in Alaska, the Yukon and Northwest Territories of Canada, and across the central Canada/U.S. boarder to as far south as New Mexico (Scott 1986). Habitats are transition to Hudsonian zone dry bunchgrass. Host plants are unknown, probably grass. Eggs are laid on grasses and sedges singly. This species is probably biennial (at least in Alberta); individuals overwinter as second, third fourth or fifth instar larvae. There is one flight each year with the approximate flight time late May ? early July (Scott 1986). Some sources consider Oeneis uhleri a subspecies of Oeneis bore.

General Description
fornecido por University of Alberta Museums
"Upperside dull ochre with a variable number of black eyespots. Underside striated black and white, median band generally not discernible. Very similar to but slightly larger than O. alberta, with a less well-defined median band, more rounded forewing shape, and more rusty upperside. O. alberta also has the ventral hindwing veins outlined in white.
Subspecies varuna is found throughout most of Alberta. The Peace River grassland populations may be an unnamed subspecies (Bird et al. 1995).

Life Cycle
fornecido por University of Alberta Museums
May be biennial in northwestern Canada, where it is more common in odd-numbered years (Scott 1986, Layberry et al. 1998). Larvae pupate under the soil, much like Riding's Satyr (Scott 1986). Males sometimes exhibit a stationary, hovering flight, possibly to locate females on the ground (Layberry et al. 1998). Uhler's Arctic can be extremely abundant in the sandhill parkland of east-central Alberta, possibly because the habit of pupating underground is facilitated by loose, sandy soil.

The larval foodplants are unknown, but may include species of fescue, junegrass and bluegrass (Festuca, Koeleria, and Poa) (Scott 1992).
