The Pandora Moth is native in the western United States. They can be found among various pine trees. This moths life cycle takes two years. They lay eggs in early summer, which hatch about two months later. The larvae (or caterpillar) then remain on the tree over winter, feeding on the foliage. The following summer the caterpillar drops out of the tree to pupate (pupa is the metamorphosis from caterpillar to adult), they bury themselves in the ground for a year, then emerge as adults the next summer.
