Common Gluphisia Moth

The common gluphisa moth has mottled white-gray to brown forewings with darker cross-stripes and a distinctive lighter white or pale-yellow patch near its costa, as well as lighter hindwings. Total wingspan typically ranges from 35–45 mm (1.4–1.8 in). Much of its abdomen and thorax are covered in short white hairs matching the rest of its coloration. Like many other species in its family, it holds its wings in a triangle or tent-like shape when at rest.

In North America, the common gluphisia moth is widespread, found from Alaska and northern Canada, down through the Rockies and across to the Alantic coast. Broadly, it can be found anywhere in the United States and Canada, save for Nunavut and the Northwest Territories.
