Peronea gallicolana Clemens, 1864 (3)
Explanation of Names
Specific epithet from Latin implexus meaning "involved, entwined."
Wingspan about 13-14 mm.
Adult - forewing light yellowish with gray triangular or semicircular patch midway along costa containing several darker gray spots; dark spot in AM area near inner margin; hindwing slightly paler than forewing, unmarked.
Quebec to British Columbia and presumably adjacent areas of United States.
Type locality: St. Martin's Falls on the Albany River, Ontario (Dr. Barnston). (4), (2)
Larvae feed on leaves of quaking aspen and willow. (5) Also reported feeding in the pine cone willow gall caused by the gall midge Rhabdophaga strobiloides.
At present, distinguishing this species from A. ferrumixtana, previously treated as a subspecies of implexana, by external features is not possible. A. implexana is a Nearctic species with DNA supported records at BOLD from across Canada, while ferrumixtana is Holarctic with records from Canada and Scandinavia.(6)

Acleris simpliciana forewing gray patch lacks darker gray spots and is broken into two unequal blotches; simpliciana may have an earlier flight period (July?) but more data is needed.
