Explanation of Names
SPECTACLED NETTLE: the larva feeds on nettle, and the adult has two raised tufts of scales on its thorax that resemble spectacles when viewed from the front - see photo on right side of this page; (a European species in the same genus is called the The Spectacle for the same reason). The merged orbicular and claviform spots are also reminiscent of spectacles, which helps to reinforce the name.
Numbers
Lafontaine & Schmidt (2010) listed four species of the genus Abrostola in America north of Mexico. (1)
Size
Forewing length 13-15 mm. (2)
Larva to about 25 mm. (3)
Identification
Adult - forewing dark gray in median area, light gray in basal and subterminal areas (some individuals are brown rather than gray); thin black AM and PM lines preceded and followed respectively by reddish-brown scales; large reniform and merged orbicular/claviform spots pale, outlined in black; ST line thick, black, jagged; terminal line thin, black, fairly straight; the joined orbicular and claviform spots resemble a pair of spectacles (a distinctive feature, although not the origin of the word "Spectacled" in the common name - see Explanation of Names above). Hindwing light gray on basal half with dark discal crescent; dark gray on outer half; fringe white with several dark spots.

Larva - body green with a series of white-bordered green chevrons dorsally, and a white lateral stripe. (3)
Range
Coast to coast in southern Canada, Washington, Oregon, and Colorado in the west, in the east south to North Carolina. Isolated population in southeast Texas. (4)
Habitat
Woodland clearings and edges where nettles grow; adults nocturnal and attracted to light (E.H. Strickland Museum).
Season
The main flight period is April to October. (5)
Food
The larvae feed on Urtica dioica (stinging nettle). (3)
Life Cycle
One generation per year in the north; larvae pupate in cocoon attached to food plant, and emerge in a few weeks.
