Amphipyra pyramidoides

Amphipyra pyramidoides, the copper underwing,[3][4] is a species of moth in the family Noctuidae. It is found in the US and southern Canada.[4]

The wingspan is 38–52 mm. Adults are on wing from July through October depending on the location. There is one generation per year.[4] They overwinter as eggs. The caterpillars are green with a white middorsal spiracular line, yellow spotting, and a hump at their eighth abdominal segment. Adult copper underwings have dappled brown forewings, and white hindwings with a black cross line and coppery orange suffusion.[5]

The larvae feed on the leaves of many broadleaf trees and shrubs, including apple, basswood, hawthorn, maple, oak, walnut, raspberry, grape, greenbrier (Smilax).[4] The larvae are active in the spring; when ready to pupate they build a shelter by rolling a leaf. Aggregations of newly eclosed adults are found under bark, etc., in mid-summer.[4]
