Synonyms and other taxonomic changes
described in 1865 by Bethune, who originally placed it in genus Calpe
Explanation of Names
CALYPTRA: from the Greek "kalyptra" (a veil), from "kalyptein" (to cover); perhaps a reference to the cloak-like forewing?
the only species in this genus in North America listed at All-Leps
uncommon in the south; locally common in the north
wingspan 33-40 mm
larva length 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 (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)
Nova Scotia to North Carolina in mountains, west to Texas, north to Saskatchewan - occasionally straying to Alberta
mesic and wet meadows; edges and clearings; adults are nocturnal and come to light
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.)
Life Cycle
one generation per year in the north

See Also
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
