Pandora pinemoths are native to the western United States and their larvae feed on the needles of several pine species. They produce one generation every two years; larvae stay on the tree through winter, drop in summer to pupate underground, and adults emerge in late June. Native peoples harvest the larvae for food, while forest managers sometimes use insecticides to limit their numbers.

Life cycle

Pandora moths are semivoltine, producing a new generation every two years. During winter the larvae remain on the tree, continuing to feed on its foliage. In the following summer they drop to the ground, burrow and pupate for a year or, in some areas, up to four years before emerging as adults.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
