Fall Webworm

Hyphantria cunea

Summary 4

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.

Habitat 5

Shrubby areas in the eastern and southern prairie ecoregion of Alberta.

Taxonomy 6

Comments: Following Lafontaine and Schmidt (2010), the traditional Arctiidae have been transferred to the family Erebidae as a subfamily (Arctiinae), with former subfamilies such as Lithosiinae now treated as tribes. The circumscription of Arctiinae remains virtually identical to recent circumscriptions of Arctiidae, but circumscriptions of some taxa within the Arctiinae have changed.
