Explanation of Names
Named for John Henry Comstock, (born 1849), entomologist and one of the founders of the Nature Study Movement of the early 20th century. His wife, Anna Botsford Comstock, was an equally prominent member of that movement, and perhaps more famous today than John.
Size
wingspan 33-39 mm
larva length to 35 mm
Identification
Adult: described by Covell (1) as having bright green FW, sometimes fading to yellowish; lines scalloped, broken, black, edged with white; note three squarish black blotches around reniform spot. HW cream; gray discal spot, partial median line, and broken shade in ST area; some green along black terminal line.
Larva: head pale green, unmarked or marked with dark brown at sides of frons; body bright or dark green with white middorsal and subdorsal stripes; prominent bicolored spiracular stripe (white and yellow on bottom, red on top); in eastern larvae, subdorsal and spiracular stripes interrupted or constricted where segments meet; subspiracular row of white or yellowish spots above abdominal prolegs
Range
southern Canada and northern United States: Newfoundland to North Carolina, west to Oregon, north to British Columbia
Habitat
coniferous and mixed forests
Season
adults fly from April or May to June
larvae present June to August or September, at which time pupation occurs
Food
in the east, larvae feed on foliage of Balsam Fir, Eastern Hemlock, spruce (Picea spp.), and possibly other conifers
in the west, principal host is Douglas-fir; other hosts include Western Hemlock, Subalpine Fir, Engelmann Spruce, White Spruce
Life Cycle
one generation per year; overwinters as a pupa in soil or debris
Remarks
An early spring moth of the north woods. Himmelman (2) calls this species "black and tennis-ball green".
