A very local, colonial species found from sea level to 7000' in a variety of mostly open, rocky habitats. Its flight is very distinctive - it wheels in circles and often does figure-eights, and is very difficult to track with the eye - and it is very "nervous" on flowers, keeping the wings in constant motion. The compound eyes are a remarkable shade of pea green. Females are conspicuously larger than males, with much broader wings; the male forewing is sharply angled at the apex.
