Explanation of Names
Calyptra Ochsenheimer, 1816
CALYPTRA: from the Greek "kalyptra" (a veil), from "kalyptein" (to cover); perhaps a reference to the cloak-like forewing?
1 species in North America listed at All-Leps
uncommon in the south; locally common in the north
wingspan 33-40 mm
larva to 35 mm
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]

Larva: white with scattered black spots along the back; broad broken black stripe along each side. Head yellow with three black spots on each side
[description by David Wagner]
Nova Scotia to North Carolina in mountains, west to Texas, north to Saskatchewan - straying to Alberta
mesic and wet meadows; edges and clearings
adults fly from June to September in the south; July and August in the north (Quebec)
larvae from May to ?
larvae feed on meadow-rue (Thalictrum spp.)

Three species of this genus in Southeast Asia have been shown to feed on the blood of large animals, including humans!
The sclerotized proboscis can perforate the skin.

forewing of Curve-lined Owlet has similar color and pattern but PM line is pale, apex has whitish shading, and hindwing is pale brownish-yellow (compare adult images 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
