Aroga epigaeella
(Chambers, 1881)
Aroga epigaeella is a small in the Gelechiidae. The is named for its larval plant, Epigaea repens (trailing arbutus). are active from spring through early autumn across a broad range of the eastern and south-central United States. The species exhibits distinctive forewing patterning with contrasting white spots against a dark ground color.

Identification
The combination of dark purple-brown forewings with paired opposing white spots (costal and ) before the apex, plus additional minute white flecks on the fold and at the end, distinguishes this from similar small gelechiids. The visible translucency of the costal spot through the wing is a notable feature. The specific epithet and association with Epigaea repens plants may aid identification where the host occurs.
Appearance
are small with dark purple-brown forewings. The forewings bear a prominent white costal spot before the apex and an opposing white spot. Before these larger spots, the wing surface is flecked with several minute white spots, with the two largest positioned on the fold and another at the end of the . The costal white spot is visible through the wing. Hindwings are fuscous (dusky gray-brown).
Habitat
Associated with supporting its plant, Epigaea repens, which grows in acidic, sandy or rocky soils in woodlands, often in pine-oak forests and along woodland edges. The has been recorded in suburban settings with suitable host plant presence.
Distribution
Recorded from Georgia, Louisiana, Maine, Maryland, Massachusetts, Mississippi, Oklahoma, South Carolina, and Texas. Distribution records also include California and additional US localities in GBIF data. The appears to be primarily eastern and south-central North American in distribution.
Seasonality
have been recorded on wing from April to September, indicating a multi-month period spanning spring through late summer.
Diet
Larvae feed on Epigaea repens (trailing arbutus). feeding habits are not documented.
Host Associations
- Epigaea repens - larval planttrailing arbutus; ericaceous shrub of acidic woodlands
Life Cycle
Larval stage feeds on Epigaea repens. Specific details of , pupal, and larval instar development are not documented. occurs from April through September, suggesting either overlapping or an extended single generation.
Behavior
are and attracted to ultraviolet light sources. No other specific are documented.
Ecological Role
As a herbivore on Epigaea repens, the larvae likely contribute to nutrient cycling and energy flow in acidic woodland . The may serve as prey for , though specific relationships are not documented.
Human Relevance
No direct economic or agricultural significance. The may be encountered by citizen scientists during lighting events, particularly during National Moth Week observations. The plant, Epigaea repens, is the state flower of Massachusetts.
Similar Taxa
- Aroga unifasciellaSimilar and size; differs in forewing pattern details and plant associations
- Other Aroga species members share small size and gelechiid ; specific spot patterns and plants distinguish A. epigaeella
- Unidentified small gelechiidsMany small gelechiids require genitalia dissection or plant confirmation for reliable identification; A. epigaeella is distinguished by its distinctive paired white spots and Epigaea association
