North American Ecology (US and Canada)Hesperia comma is a year-round resident across much of Canada and from Alaska south to California and west to Texas, and is also in northern Africa, Europe and Asia (Scott 1986). Habitats are open woodland and grassland. Host plants are multiple genera of grasses and sedges (Cyperaceae) in Japan. Eggs are laid haphazardly on or near the host plant. Individuals overwinter as eggs, and as older larvae or pupae in the Arctic. There is a variable number of flights each year depending on latitude with one flight between June 1-Sept.30 in much of the range, two flights between June 15- Oct. 15 in southern Nevada, and flying biennially in the Arctic, between July 1-July 31 (Scott 1986).
