Fall Webworm - Hyphantria cunea

The fall webworm, "Hyphantria cunea", is a moth in the family Arctiidae known principally for its larval stage, which creates the characteristic webbed nests on the tree limbs of a wide variety of hardwoods in the late summer and fall. It is mainly an aesthetic pest, and is not believed to harm otherwise healthy trees. It is well known to commercial tree services and arboriculturists.
