Olethreutes troglodanum
(McDunnough, 1922)
Olethreutes troglodanum is a of tortricid in the Tortricidae, Olethreutinae. First described by McDunnough in 1922, this species belongs to a diverse of small moths commonly known as tortrix moths or leafroller moths. The genus Olethreutes contains numerous species, many of which are associated with specific plants and exhibit characteristic rolling or folding on leaves during larval development. Like other members of its genus, O. troglodanum is likely a small moth with relatively nondescript coloration typical of many Olethreutinae.

Identification
Identification to level within Olethreutes typically requires dissection and examination of genitalia structures, as many species are externally similar. The specific epithet 'troglodanum' (from Latin 'troglodyta' meaning cave-dweller, with suffix '-anum') may suggest an association with dark or sheltered , though this is speculative. Distinguishing O. troglodanum from would rely on subtle differences in wing pattern, particularly the configuration of markings on the forewing, and confirmed through microscopic examination of male or female genitalia. No published keys or diagnostic resources specifically addressing this species were found in the provided sources.
Appearance
As a member of the Olethreutes, this is expected to be a small with wingspan likely in the range of 10-20 mm, typical for the genus. Tortricid moths in this genus generally have forewings that are somewhat rectangular to triangular in shape, often with muted coloration in shades of brown, gray, or ochre, frequently with variable banding or mottled patterns. The hindwings are typically paler and more uniform. Specific diagnostic features for O. troglodanum would require examination of genitalia or detailed wing pattern analysis.
Distribution
Known from Vermont, United States, based on distribution records in GBIF. The iNaturalist database indicates four observations, suggesting this is a rarely recorded or genuinely uncommon with limited documented occurrence data.

Taxonomic note
The was originally described by James Halliday McDunnough in 1922. McDunnough was a prominent Canadian entomologist who made significant contributions to North American lepidopteran , particularly for microlepidoptera.
Data scarcity
This appears to be poorly documented in public databases and literature. The four iNaturalist observations and limited GBIF records suggest either genuine rarity, cryptic habits, or undercollection. No published or ecological studies were located in the provided sources.
