Eupithecia appendiculata
McDunnough, 1945
Eupithecia appendiculata is a small in the Geometridae, first described by James Halliday McDunnough in 1945. It belongs to the Eupithecia, commonly known as 'pug' moths, recognized by their narrow wings and distinctive resting posture. The has been documented as a visitor to apple flowers, contributing to pollination services in agricultural settings.

Identification
Members of the Eupithecia are readily recognized by their narrow wings and unique resting posture. -level identification within Eupithecia typically requires examination of genitalia or other microscopic characters. Eupithecia appendiculata can be distinguished from similar western North American Eupithecia species by specific morphological details not accessible through casual observation.
Appearance
Wingspan approximately 15 mm. As a member of the Eupithecia, it has narrow wings and a characteristic resting posture typical of pug moths. Specific coloration and pattern details for this are not documented in available sources.
Habitat
Found in dry, mixed conifer forest with oaks at elevations around 7,000 feet. Associated with supporting good floral diversity. Specific microhabitat preferences for this are not documented.
Distribution
Western North America: Utah, Colorado, Idaho, California, and Baja California.
Behavior
, attracted to blacklights. Has been observed visiting apple flowers at night, where it may contribute to pollination.
Ecological Role
Documented as a of apple flowers. As a member of the Geometridae , larvae (if following typical patterns) may feed on plant material, though specific plants for this are not recorded.
Human Relevance
Identified as one of the contributing to pollination in apple orchards, demonstrating that moth species can provide valuable services in agricultural settings.

Pollination Research
A Eupithecia , likely this or a , was photographed by Stephen Robertson, Ph.D., during a 2021 study on apple pollination published in the Journal of Economic Entomology. The study demonstrated that nocturnal , including moths, contribute significantly to apple production.
