Adult Food: Not reported.
Habitat: Edges of bogs, old brushy fields, open places near small streams.

Conservation: Subspecies claytoni in Maine should be conserved.
NCGR: G4 - Apparently secure globally, though it might be quite rare in parts of its range, especially at the periphery.
Management Needs: Manage and conserve habitat of Clayton\'s copper in Maine.
