Gray Hairstreaks, Strymon melinus, are common butterflies found from southern Canada, throughout the US, and as far south as Venezuela. These are small butterflies with a wingspan of only 7/8 – 1 3/8 inches. Male Gray Hairstreaks can be found perching on shrubs and small trees as they await the arrival of a receptive female.
Females lay their single eggs on the flowers of their chosen host plant. Host plants include clover, mallow. pea, and a diverse variety of other plants. The fruits and flowers provide meals for younger caterpillars while older caterpillars dine on the leaves.
Look for Gray Hairstreaks in open and disturbed areas where native plants including goldenrod, dogbane, clover, and milkweed thrive.
