|scientific name Grammia blakei |
common name Blake's Tiger
Short grass and mixed grass prairie, especially in native range pastures grazed by livestock.
Mid May to early June.
Alberta's smallest species of Grammia. Similar to G. nevadensis, but blakei can usually be distinguished by the more reduced forewing markings, more "pointy" appearance of the forewing, and overall smaller size.
There is a partial second brood in August in some years, especially in the southern part of the range (Byers, 1988). The adults of this species are apparently strictly diurnal, flying in the afternoon and early evening.
Larvae feed on various grasses (including spring cereal crops) in early spring, and are occasionally pests in native range pastures (Byers, 1988).
Manitoba west to Alberta, south to Arizona and New Mexico.
