About Polygonia faunus (Edwards, 1862)
Polygonia faunus, commonly called the green comma, is a species of butterfly with a wingspan that reaches 45–64 mm. These butterflies are usually uncommon, and have extremely ragged wing edges. The species shows considerable geographic variation across its range. The upperside of the wings is reddish brown with wide dark borders, and the hindwing border includes a row of yellow spots. The underside of the wings is grey-brown overall, with a lighter outer half. Males have greenish submarginal spots that resemble lichen, and the center of each hindwing has an L- or C-shaped silver spot. Females have more uniform, dull gray undersides to their wings. This species is native to boreal regions of North America. Its distribution extends from central Alaska south to central California and northern New Mexico, and also stretches across the Great Lakes region to New England, the Maritimes, and the southern Appalachians. Green commas primarily inhabit forests, mountain woodlands, areas near streams, and canyons.
