Amphipyra pyramidoides, the copper underwing,[2][3] is a species of moth in the family Noctuidae. It is found in the US and southern Canada.[3]
The wingspan is 38–52 mm. Adults are on wing from July through October depending on the location. There is one generation per year.[3] They overwinter as eggs.
The larvae feed on the leaves of many broadleaf trees and shrubs, including apple, basswood, hawthorn, maple, oak, walnut, raspberry, grape, greenbrier (Smilax).[3] 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.[3]
