Eupithecia fletcherata
Taylor, 1907
Fletcher's larch looper
Eupithecia fletcherata, known as Fletcher's larch looper, is a North American in the Geometridae described by George Taylor in 1907. The is named in honor of Dr. James Fletcher, a prominent Canadian entomologist. It belongs to the large Eupithecia, commonly called 'pugs,' which are recognized by their narrow wings and distinctive resting posture. The species has been documented visiting apple flowers, contributing to pollination services.

Identification
Members of the Eupithecia, including E. fletcherata, are recognized by their narrow wings and unique resting posture. Specific identification to level typically requires examination of genitalia characters, as many Eupithecia species are visually similar. The species can be distinguished from other northeastern North American Eupithecia by a combination of wing pattern and genitalic features, though precise diagnostic characters require reference materials.

Distribution
Canada: Newfoundland and Labrador, Nova Scotia, New Brunswick, Quebec, Ontario, and Manitoba. United States: northeastern region including Ohio and Missouri.
Host Associations
- Larix laricina - larval : tamarack or eastern larch. The epithet 'fletcherata' and common name 'Fletcher's larch looper' strongly indicate this association, though direct documentation of larval feeding requires verification.
Behavior
have been observed visiting apple flowers at night, where they function as . This was documented in a 2021 study on apple pollination in Arkansas, where Eupithecia were photographed on apple flowers.
Ecological Role
contribute to pollination of flowering plants, including agricultural crops such as apple. The ' role in this service was highlighted in research demonstrating that nocturnal can achieve similar seed set to pollinators in apple production.
Human Relevance
The is named in honor of Dr. James Fletcher (1852-1908), a pioneering Canadian entomologist and agriculturalist who was instrumental in establishing entomology in Canada. have been documented as in apple orchards, suggesting potential value in agricultural pollination services.
