Identification

The can be distinguished from North Archips species by its status and known distribution in the northeastern United States. Accurate identification requires examination of or molecular methods, as external overlaps with other . The specific epithet 'fuscocupreanus' suggests - coloration, but this should not be relied upon for definitive identification.

Appearance
