Eupithecia nonanticaria
Ferris, 2007
Eupithecia nonanticaria is a small geometrid described by Clifford D. Ferris in 2007. It is restricted to high-elevation mixed coniferous forests in the southwestern United States and northern Mexico, specifically the Pinos Altos Range, Black Range, and Chiricahua Mountains. are active during a narrow window from late July to mid-August. The is one of many Eupithecia "pugs" that are challenging to identify without detailed examination.

Identification
Members of Eupithecia are recognized by their narrow wings and distinctive resting posture, earning them the "pugs." Definitive identification of E. nonanticaria likely requires examination of genitalic characters or other microscopic features, as is typical for this -rich . The species may be distinguished from sympatric Eupithecia by geographic restriction to high-elevation mixed conifer forests above 1,760 meters in the southwestern U.S. and adjacent Mexico, combined with its specific period in late July to mid-August.
Appearance
A small with forewing length of 9.5–11 mm in males and 9–11 mm in females. As a member of Eupithecia, it possesses narrow wings and exhibits the characteristic "pug" resting posture with wings held flat or slightly overlapping. Specific coloration and pattern details are not documented in available sources.
Habitat
Mixed coniferous forests at elevations above 1,760 meters. The is characterized by conifer dominance with associated understory vegetation.
Distribution
Known from the Pinos Altos Range and Black Range in New Mexico, the Chiricahua Mountains in Arizona, and Chihuahua in Mexico.
Seasonality
are on wing from late July to mid-August. This represents a narrow, presumably period.
Behavior
are attracted to light, as documented by blacklight surveys in the Pinos Altos area. The has been observed visiting flowers, including apple blossoms, suggesting nectar-feeding .
Ecological Role
Likely contributes to pollination services in its montane . A 2021 study documented Eupithecia , including this , visiting apple flowers and functioning as . The caterpillars, if consistent with other Eupithecia species, may feed on flowers or seeds of plants, though specific hosts remain unknown.
Human Relevance
Documented as a participant in pollination of apple crops, indicating potential value in agricultural and natural . No known negative impacts.
Similar Taxa
- Other Eupithecia speciesExtremely difficult to distinguish without microscopic examination; many overlap in size, coloration, and pattern. Geographic range and elevation may help narrow possibilities.
