the only species in this genus in North America listed at All-Leps
uncommon in the south; locally common in the north
Size
wingspan 33-40 mm
larva length to 35 mm
Identification
Adult: forewing light brown with darker brown bands, pointed apex, and angular outer margin; PM line sharp, nearly straight, slanting from apex to inner margin; dark scaling along veins; note two scale tufts on inner margin, the basal tuft forming a prominent lobe, and the distal one a small sharp point; hindwing grayish-brown; antennae bipectinate in both sexes
[adapted from description by Charles Covell (1)]

Caterpillar: white with scattered black spots along the back; broad broken black stripe along each side. Head yellow with three black spots on each side. To 3.5 cm (2)

Curve-lined Owlet (Phyprosopus callitrichoides) forewing has similar color and pattern but PM line is pale, apex has whitish shading, and hindwing is pale brownish-yellow (compare adult images or both species by Jim Vargo at MPG); Curve-lined Owlet also has a southern distribution (doesn't occur in Canada), the moth is smaller, and the larva is very different
