|scientific name Holoarctia sordida |
common name Sordid Tiger
High alpine scree slopes and rock fields.
Available flight dates range from mid June to the first week of August.
Hindwing is translucent grey, sometimes with some ochre colouring. No pink or yellow. Superficially similar to Grammia quenseli, but H. sordida lacks the whitish lines along the forewing veins, and has at least one pale transverse band on the forewing.
Adults are diurnal, and are strong fliers. Members of this genus take two years to develop (Freina & Witt, 1987), but it appears that adults can occur every year.
Unknown. Probably various herbs and grasses. H. cervini is reportedly prefers grasses, saxifrages (Saxifragaceae), and members of the primrose family (Primulaceae).
So far only known from a few localities in the Rocky Mountains of B.C. (Pink Mountain) and Alberta (South to Chester Lake, Peter Lougheed Prov. Park).
