Narrow, relatively small wings typical of Eupithecia pugs. Resting posture with wings held flat or slightly overlapping, often appearing slender and delicate. Coloration and pattern details specific to this are not well documented in available sources.
Habitat
Dry, mixed conifer forest with oaks at moderate elevations (around 7,000 feet). Associated with supporting good floral diversity.
Distribution
Western North America; specifically documented from Arizona (Coconino County, type locality implied by name) and observed in New Mexico (Grant County).
Seasonality
active in late summer; documented observations from August.
Behavior
; attracted to artificial lights. Has been observed visiting apple flowers at night, suggesting nectar-feeding and potential role in pollination.
Ecological Role
