Ceranemota tearlei

Distinguished from related Ceranemota species by geographic range and association with specific host plants. Adults fly late in the season (August-October), which may help separate from earlier-flying congeners. Genitalia examination may be required for definitive identification.

Adults have forewings with a pattern typical of the genus. Hindwings are lighter grey with somewhat darker markings.

Higher elevation spruce-fir and mixed hardwood-conifer forests; lower elevation ponderosa pine forests; quaking aspen forests; moist riparian areas along creeks.

Western North America: British Columbia and central Alberta south to central California in the west, and to Utah and Colorado in the Rocky Mountains.

Adults on wing from late August to October. One generation per year.

Larvae feed on Amelanchier alnifolia (Saskatoon serviceberry), Sorbus scopulina (mountain-ash), and Salix species (willows). Adult diet unknown.

Univoltine (one generation per year). Larval stage feeds on host plants; pupation and adult emergence timing not documented.

Larval herbivore on woody shrubs and trees in montane and riparian forest ecosystems. Specific ecological functions (pollination, predation, decomposition) not documented.

No documented economic or cultural significance. Occasionally encountered by naturalists and moth enthusiasts in western North America.
