Green Commas join at least 8 other butterfly species in Montana with the distinction of being hardy little insects. The Green Commas we are seeing now will overwinter in the adult stage and become active again once the weather becomes warm enough in the late winter or early spring. Since they can feed on tree sap and minerals from carrion and dung, they are often found flying when snow is still on the ground – well before the first flowers of the season are in bloom. Preferred habitat includes riparian woodlands and wet meadows.

Size: 1.75 – 2.5 inch wingspan
