Humped Green Fruitworm

CRANBERRIES

Humped Green Fruitworm
Order: Lepidoptera || Family: Noctuidae
Amphipyra pyramidoides (Guenée)

This pest--with a very prominent hump (see photo)--has an affinity for apples, but in addition to cranberry, it has also been collected from plum, peach, black cherry, flowering almond, and crab apple, as well as on 20 deciduous trees and shrubs (basswood, elm, oak, white birch, and willow especially). It goes through just one generation per year. Its numbers in Maine looked for awhile to be on the rise most everywhere, but their numbers have declined again in recent years, and generally only a few are found per set of 25 sweeps at any one time. It is important to remember that the humped green fruitworm is in its larval stage early in the season, and so all of its feeding is done solely on early-season foliage as opposed to the berries. It will feed on vines during the day and will not leave the vines at night to rest in the soil like true cutworms do. Humped Green Fruitworm larva
