The has experienced significant regional decline and is considered extirpated in Connecticut. Larvae are specialized feeders on Vaccinium species.

Identification
may be distinguished from other Drasteria by geographic range and association with coastal Vaccinium habitats. Larval identification supported by plant association and the distinctive brown with white stripes combined with brown body bearing light brown and blackish lines. Similar species in the Drasteria overlap in eastern North America and require examination of genitalia or molecular markers for definitive identification.
Habitat
Coastal areas. Associated with supporting Vaccinium , which serve as larval plants. Specific microhabitat preferences for are not documented.
Distribution
North America. Documented from coastal Maine, New Jersey, Pennsylvania, and Texas. Historical records from Connecticut, where the is now believed extirpated and listed as a species of special concern.
Diet
Larvae feed on Vaccinium . feeding habits are not documented.
Host Associations
- Vaccinium - larval food plantSpecific Vaccinium not identified in available sources.
Life Cycle
Complete with , larva, pupa, and stages. Larvae reach 26 mm at full growth. Timing of life stages and strategy are not documented.
Behavior
have been observed at light stations. Larvae presumably feed externally on plant foliage based on typical erebid larval habits, though specific feeding is not described.
Ecological Role
Larval herbivore on Vaccinium. Specific roles in or processes are not documented.
Human Relevance
Listed as a of special concern and believed extirpated in Connecticut, indicating conservation concern in parts of its range. No documented economic or cultural significance.
