Species implexana (Acleris implexana - Hodges#3522)
Hodges Number
3522
Synonyms and other taxonomic changes
Acleris implexana (Walker, 1863) (1)
Sciaphila implexana Walker, 1863 (2)
Peronea gallicolana Clemens, 1864 (3)
Explanation of Names
Specific epithet from Latin implexus meaning "involved, entwined."
Size
Wingspan about 13-14 mm.
Identification
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.
Range
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)
Food
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.
Remarks
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)
See Also
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.
