These coppers are currently making their second and last appearance for the year in western Montana. We have two flights of Purplish Coppers — the first from May into July and the second from August into October. In this last flight, the females will lay eggs that will overwinter. The caterpillars will emerge soon after the return of spring-like temperatures.
