Eupithecia vargoi
Eupithecia vargoi is a of inchworm in the Geometridae. Like other members of the Eupithecia, it is characterized by narrow wings and a distinctive resting posture. The species has been documented visiting apple flowers at night, contributing to pollination of fruit crops. It belongs to a diverse genus of small moths commonly known as "pugs," many of which are challenging to identify to species level without detailed examination.

Identification
Members of the Eupithecia ("pugs") are recognized by their narrow wings and unique resting posture. -level identification within this genus is notoriously difficult and typically requires dissection of genitalia. Eupithecia vargoi specifically cannot be reliably distinguished from by external appearance alone based on available documentation.
Habitat
Associated with mixed conifer forest at moderate elevations (approximately 7,000 feet), based on regional occurrence records for related in the southwestern United States. Specific microhabitat preferences for E. vargoi are undocumented.
Distribution
Documented from New Mexico, United States. Precise range boundaries are unknown due to limited observation records (only one documented observation in available sources).
Seasonality
Active period not specifically documented for this . of Eupithecia species in the southwestern United States have been observed in late summer (August).
Behavior
Has been observed visiting apple flowers at night, indicating activity and participation in nighttime pollination. This aligns with documented nocturnal pollination services provided by Eupithecia in agricultural settings.
Ecological Role
Contributes to pollination of flowering plants, including agricultural crops such as apple. In this capacity, provides services that complement daytime activity.
Human Relevance
Documented as a visitor to apple flowers, contributing to pollination in fruit production systems. This dual role illustrates that often categorized as neutral or potentially pest-associated can provide valuable agricultural services.

Taxonomic Note
The Eupithecia is one of the most -rich genera of Geometridae, with many species requiring taxonomic revision. Identification challenges contribute to sparse documentation for individual species.
Research Context
Eupithecia vargoi was specifically mentioned in a 2021 study on apple pollination published in the Journal of Economic Entomology, where it was photographed visiting apple flowers at night alongside other .
