help Gray Comma FAQ
How do I tell a Gray Comma apart from an Eastern Comma butterfly?
The Gray Comma (Polygonia progne) shows heavy gray or gray-brown marbling on the underside of its hindwings and more strongly jagged wing margins than the Eastern Comma. Both carry the small silvery comma-shaped mark that gives the group its name, so the underside texture is the key clue.
Where does the Gray Comma butterfly live?
It is a North American species found across the northeastern United States and southern Canada, extending west toward the northern prairies and Rockies. It favors deciduous and mixed woods, clearings, and streamsides rather than open fields.
What do Gray Comma caterpillars eat?
The larvae feed primarily on Ribes species, namely gooseberries and currants. This separates them from many anglewings that rely on elm, nettle, and hops as host plants.
When is the best time of year to see Gray Commas?
Adults hibernate through winter and reappear very early in spring, with a second flight in late summer and fall from a second generation. In late-season woodlands, adults often feed on sap flows, rotting fruit, and asters.
