scientific name    Boloria freija    

common name     Freija Fritillary

habitat
Coniferous forest clearings.

seasonality
One yearly flight, peaking from late May to early July depending on elevation.

identification
A relatively small Boloria (Wingspan 28 - 38 mm), recognizable by the median row of whitish, arrowhead-shaped marks on the hindwing underside. Remarkably, our populations are apparently not distinguishable from those of the nominate populations in Scandinvia, and are subspecies freija.

life history
The immature stages of North American populations have not been fully described. The half-grown larva is dark brown with pale patches and many spines (Scott 1986). Eggs hatch in about 12 days (Bird et al. 1995). This is the first Boloria to appear in the spring, flying together with other early spring species such as Spring Azures, elfins and post-hibernation nymphalids.

conservation
Not of concern.

diet info
Females lay eggs on Bearberry (Arctostaphylus uva-ursi) in Alberta (Scott 1986). Larvae feed on Vaccinium caespitosum in Washington (Shepard in Howe 1975), and females also oviposit on this plant in Manitoba (Klassen et al. 1989).

range
Circumpolar, the North American range extending from Alaska across the Arctic Archipelago to Newfoundland and south to Washington, Montana and the northwest Great Lakes region. Dusjunct populations in the southern Rockies (Scott 1986).
