The Arctic Fritillary or Purplish Fritillary (Boloria chariclea) is a butterfly of the Nymphalidae family. It is found in the northern part of the Palearctic ecozone and the Nearctic ecozone.
Description
The upper sides of the wings are orange-brown with small dark markings in neat rows. The underside of the forewing is orange with dark markings. The underside of the hindwing has a margin of small white spots topped with brown. Inside this are black inwardly pointing triangles with scant white areas. The median band is pale yellow-brown to rusty-brown mottled with white and with wavy, sometimes broken, black lines. The length of the forewings is about 17 mm (0.67 in). The butterfly flies from July to August depending on the location.[1][2]
Distribution and habitat
The Arctic Fritillary has a Holarctic distribution. In Europe it is found in northern Lapland and Russia. In North America it is found in Alaska and much of Canada, the north Cascades, the Rocky Mountains southwards to Utah and northern New Mexico, northern Minnesota, northern Maine and the White Mountains of New Hampshire. Its typical habitat is tundra, taiga, Alpine meadows, stream verges and acid bogs.[1]
Life cycle
The males patrol along the edges of bogs and in valleys and wait for the arrival of females. The eggs are laid singly underneath the leaves of the host plant. In North America the larvae feed on Viola species, dwarf willows (Salix) and possibly blueberries (Vaccinium)[1] while in Europe it is believed to feed on yellow wood violet (Viola biflora) and Arctic white heather (Cassiope tetragona).[2] Depending on location, the larvae take one or two years to develop into adults, newly hatched caterpillars hibernating during the first winter and fourth-stage caterpillars hibernating during the second.[1]
