Eupithecia prostrata
McDunnough, 1938
Eupithecia prostrata is a of pug moth in the Geometridae, described by James Halliday McDunnough in 1938. It is one of approximately 140 Eupithecia species known from North America. Members of this are commonly called 'pugs' and are recognized by their narrow wings and distinctive resting posture. The species has been documented visiting apple flowers at night, contributing to pollination services.

Identification
As a member of the Eupithecia, this shares the characteristic 'pug' : narrow, relatively short wings and a unique resting posture with wings held tightly against the body. Positive identification to species level typically requires examination of genitalia or other microscopic characters, as many Eupithecia species are superficially similar. The genus is distinguished from other geometrid moths by wing shape and resting posture, but species-level determination is challenging without dissection.
Distribution
Known from California and Arizona in the southwestern United States. Distribution records in GBIF confirm presence in North America.
Behavior
Has been observed visiting apple flowers at night, indicating activity and potential role in pollination. Like other geometrid moths, are likely attracted to light sources.
Ecological Role
Documented as a visitor to apple flowers, contributing to nighttime pollination services in agricultural settings. This dual role as both herbivore (in larval stage, though specific plants unconfirmed for this ) and illustrates the multifunctional nature of .
Human Relevance
Contributes to pollination of apple crops, providing services that complement daytime activity. This role highlights the value of 'pest' groups in agriculture beyond their larval feeding habits.
Similar Taxa
- Other Eupithecia speciesOver 140 Eupithecia occur in North America, most requiring genital dissection for reliable identification. Wing patterns and size overlap extensively across species.
- Other Geometridae (inchworm moths)Shares characteristics of slender body and broad wings, but pugs are distinguished by narrower wings and tighter resting posture.

Taxonomic note
The epithet 'prostrata' refers to the prostrate or low-growing habit, possibly alluding to larval plant characteristics or collection circumstances, though the etymology is not explicitly documented in available sources.
