Acleris implexana
Acleris implexana is a small tortricid moth with a wingspan of 13–14 mm, distributed across boreal regions of Europe and North America. Adults are active in late summer and autumn, with larvae feeding on Pinus and Salix species. A notable ecological association involves larvae feeding within pine cone willow galls induced by the gall midge Rabdophaga strobiloides. The species is represented by two recognized subspecies: A. i. implexana in North America and A. i. ferrumixtana in Europe.
Catocala briseis
Briseis Underwing, Ribbed Underwing
Catocala briseis is a medium-sized underwing moth in the family Erebidae, distributed across the North American boreal forest region. Adults are active from July to September and possess the characteristic underwing morphology: cryptic forewings that conceal brightly patterned hindwings. The species was first described by William Henry Edwards in 1864.
Catocala concumbens
Pink Underwing, Sleepy Underwing
Catocala concumbens, commonly known as the pink underwing or sleepy underwing, is a medium-sized moth in the family Erebidae. The species was first described by Francis Walker in 1858. It is distinguished by its cryptic forewings and brightly colored hindwings, a characteristic defensive trait of the genus Catocala. The moth occurs in eastern North America, extending westward across the Prairie Provinces to eastern Alberta. Adults are active in August, with larvae feeding on Populus and Salix species.
Catocala grotiana
Grote's Underwing Moth, Grote's Underwing
Catocala grotiana is a large underwing moth in the family Erebidae, first described by James S. Bailey in 1879. The species is characterized by its cryptic forewings and brightly colored hindwings, a defensive trait common to the genus Catocala. It occurs in the western United States, with documented records from Arizona, Utah, Colorado, Washington, and areas north and east of California. Adults are active in late summer, with larvae feeding on Populus and Salix species.
Catocala marmorata
Marbled Underwing
Catocala marmorata, known as the marbled underwing, is a large moth in the family Erebidae. The species was first described by William Henry Edwards in 1864. Adults are active from July to September, with likely one generation per year. The larvae feed on Populus and Salix species.
Epinotia nisella
Grey Poplar Bell, Yellow-headed Aspen Leaftier
Epinotia nisella is a small tortricid moth with a Holarctic distribution across northern Eurasia and northern North America. First described by Clerck in 1759, it is highly polymorphic in forewing coloration, showing extensive variation in grey, black, and brown patterns. The species is closely related to E. cinereana, from which it was recently reinstated as distinct based on DNA barcodes and genital morphology. Larvae feed on catkins and leaves of Populus and Salix species.
Exaeretia ciniflonella
Scotch flat-body
Exaeretia ciniflonella is a small moth in the family Depressariidae with a trans-Palearctic and western Nearctic distribution. Adults have a wingspan of 17–24 mm and are active from July through August, with individuals sometimes reappearing in early spring after overwintering. Larvae develop within rolled or folded leaves of birch, poplar, and willow.
Notodonta torva
Large Dark Prominent, Northern Finned Prominent
Notodonta torva is a moth in the family Notodontidae, first described by Jacob Hübner in 1803. It is widespread across Europe and extends eastward through Asia to China, Korea, and Japan, with rare occurrences as an immigrant to Great Britain. The species is bivoltine in western Europe, producing two generations per year. Larvae feed primarily on poplar and willow species.
Pseudosciaphila duplex
Poplar Leafroller Moth, Aspen Leaftier, Spotted Aspen Leafroller
Pseudosciaphila duplex is a tortricid moth native to North America, commonly known as the poplar leafroller moth or aspen leaftier. Adults are active during summer months and possess a wingspan of 20–25 mm. The species is notable for its larval association with deciduous trees in the genera Populus, Betula, and Salix, where larvae feed on leaves.
