There’s only one generation of this butterfly each year …but you can see it at two different times of the year. How’s that possible? Like Montana’s state butterfly (the Mourning Cloak), Green Commas (along with several other species of commas and tortoiseshells) overwinter as adult butterflies. The one pictured here emerged as an adult sometime last summer (late July or August), overwintered, and then took to the air once again this spring to find a mate and create the next generation. They can be found across much of the northern US and south into New Mexico along the Rocky Mountains.
