Explanation of Names
At Words by William Whitaker, "viridata" translates to "become green". This is most certainly referring to the wing coloration.
wingspan 18-20 mm (1)
Adult: forewing a mix of brownish-gray and yellowish-green shading with broken transverse lines and many black longitudinal dashes along veins; hindwing light brownish-gray with faint median line and discal dot but appearing virtually unmarked from a distance; abdomen lacks blackish band near base
Newfoundland to British Columbia and adjacent northern states, south in the east to Florida, and south in the west to Colorado and Oregon
mature deciduous and mixed woodland; adults are nocturnal and come to light
adults fly from April to July
larvae feed on flowerheads of Possumhaw (Viburnum nudum [=cassinoides]) [Handfield, p. 256]
Life Cycle
one generation per year

Green Pug (Pasiphila rectangulata) forewing has several dark wiggly continuous (not broken) lines crossing it; the hindwing has the same color and pattern as the forewing, and the abdomen has a broad blackish band near the base (lacking in Acasis viridata); compare images of both species at CBIF and at MPG
