Description
While generally similar to most other Pyrgus species, this species has a greyer brown background colour with bold white spots on both the forewing and hindwing. Unlike most other Pyrgus species, the veins on the underside are obviously lined white. Wingspan is 25 to 33 mm. Seitz describes it- H. centaureae Rambur. (86 a) large, dark, with very distinct white dots and spots. Underside of hindwing dark brown or blackish with a greenish tint. The brown band which forms the outer border of the white band, bears spots and forms the inner border of a white terminal band, which appears divided by a row of strong brown dots so that there are two white bands beyond the median band. Scandinavia, Finland, the Altai; also in North America; in June and July.
Biology
It occurs in the northern taiga, forest tundra and southern shrub tundra. One generation is produced per year in its southern range from March to May. Two years are required for each brood in the subarctic. Larval food plants include cloudberry (Rubus chamaemorus), wild strawberry (Fragaria virginiana), dwarf cinquefoil (Potentilla canadensis), and varileaf cinquefoil (Potentilla diversifolia).
