Size
wingspan 8-10 mm, based on three Internet photos
Identification
Adult: forewing slender, almost parallel-sided, with wide fringe on outer margin, especially at anal angle, where the fringe forms a tuft that projects upward when the moth is at rest with its wings held together over the abdomen; forewing dark gray or blackish with three large orangish-yellow spots (sometimes reduced): one crossing the wing near the base, a second spot halfway along the inner margin, and another spot about two-thirds distance along costa; hindwing thin, gray, with wide fringe of hair-like scales

northeastern North America, introduced from Europe or north Africa, where it is widespread
