Eupithecia flavigutta
(Hulst, 1896)
Eupithecia flavigutta is a small in the Geometridae, first described by George Duryea Hulst in 1896. It is restricted to montane forest in the southwestern United States, specifically Colorado, eastern Arizona, and southwestern New Mexico. The has a wingspan of 16–20 mm. Members of the Eupithecia, commonly called 'pug' moths, are recognized by their narrow wings and distinctive resting posture.

Identification
Members of Eupithecia are readily recognized by their narrow wings and unique resting posture, earning them the 'pug' . -level identification within this typically requires examination of genitalia or other minute characters not visible to standard photography or unaided observation. E. flavigutta is distinguished from other Eupithecia species by geographic range (Colorado, eastern Arizona, southwestern New Mexico) and presumably by subtle morphological differences described in the original 1896 description.
Appearance
Small with wingspan 16–20 mm. As a member of the Eupithecia, it possesses narrow wings held in a characteristic resting posture. Specific coloration and pattern details for E. flavigutta are not documented in available sources.
Habitat
Montane forest areas, specifically dry mixed conifer forest with oak components at elevations around 7,000 feet. The supports good floral diversity as indicated by associated insect fauna.
Distribution
United States: Colorado, eastern Arizona, and southwestern New Mexico. Records indicate presence in montane forest zones of these regions.
Behavior
; attracted to artificial light sources including blacklights and porch lights. Has been observed visiting apple flowers at night, contributing to nocturnal pollination activity.
Ecological Role
function as . A study on apple pollination documented Eupithecia visiting apple flowers at night, demonstrating their contribution to nighttime pollination services in agricultural settings.
Human Relevance
Documented as a of apple crops, indicating potential value in agricultural . No known negative impacts.

Taxonomic note
The specific epithet 'flavigutta' (from Latin flavus = yellow, gutta = spot) suggests yellow spotting in the original description, though this is not explicitly documented in available sources.
