Explanation of Names
Latin for "half-moon"
Tailless, dorsal drab gray, underwing grayish to brown, with the FW usually having a line of dark dots circled in white, and the HW can have some whitish dots.

Distinction from S. fuliginosum as a distinct species is debated, and needs further study in potential zones of contact. Distinguished from that species by the presence (sometimes faint) of a "stigma" or "sex brand" on the upper front wing of the males, and by distribution. Zone of contact should be near the east base of the Sierra Nevada and northward across southwestern Oregon.
Wyoming and Colorado, west to east-central California, and north to British Columbia.
Open, usually exposed areas in association with Lupines (Lupinus species) and usually also with Sagebrush (Artemisia species).
