scientific name    Erebia mancinus    

common name     Taiga Alpine

habitat
Sparsely treed spruce bogs.

seasonality
One flight per year, peaking in June.

identification
The upperside is dark chocolate-brown with a row of 4 to 5 subapical dots surrounded by a diffuse, rust-orange patch. The underside has a greyish frosting, with a faint, slightly darker median band and a white median spot; no hindwing eyespots. The only similar species in Alberta is the Common Alpine (E. epipsodea), but the latter always has hindwing eyespots. There are no described subspecies; the Taiga Alpine was thought to be the same species as E. disa until Layberry et al. (1998) provided evidence of separate species status. The type locality of mancinus is Rock Lake, near Jasper, AB.

life history
Undescribed. Adults fly among partially shaded, open spruce stands in spahgnum bogs, and are often found together with Jutta Arctics. The life cycle takes two years to complete, and adults may be present only in alternate years at a particular site (Klassen et al. 1989).

conservation
Not of concern.

diet info
The larval hosts are unrecorded, but are probably grasses or sedges. Adults do not often nectar, and occasionally mud-puddle (Bird et al. 1995).

range
Alaska to Labrador, south to the northwestern Great Lakes region and Canmore, Alberta, with an isolated population in the Cypress Hills of southwestern SK (Layberry et al. 1998, Bird et al. 1995).
