The dorcas copper is a small northern butterfly that is typically found around bogs or other wetland areas in Alaska, Canada, and parts of northern United States. There is typically one brood per summer from June through August. They are very similar looking to the purplish copper.
Females lay their eggs one at a time on the underside of the leaves of their host plant, which are cinquefoils. In the fall the eggs fall to the ground where they will overwinter as eggs. In spring the new caterpillars will emerge and crawl back up the new host plants and begin to eat the leaves.
