Ethmia albistrigella
Ethmia albistrigella is a small moth in the family Ethmiidae, distributed across western North America from British Columbia to California. The species is characterized by a distinctive white longitudinal streak on dark forewings. Two subspecies are recognized: the nominate form and the Arctic-Alpine race icariella, which is restricted to California and exhibits darker coloration. Adults are active from late spring through summer, and larvae feed on specific host plants in the Boraginaceae family.
