starts withThe wingspan of Polygonia faunus can reach about 45–64 mm. These usually uncommon butterflies show extremely ragged wing edges. They are geographically rather variable. The upperside of their wings is reddish brown with wide dark borders. The hindwing border contains a row of yellow spots. The underside of the wings is grey-brown, but the outer half is lighter, with greenish lichen-simulating submarginal spots in the males. Moreover, the hindwings have a L or a C-shaped silver spot in middle. In the females the wings are more uniform, dull gray below.
This species can be found in the boreal North America, from central Alaska south to central California and northern New Mexico. It is also present across the Great Lakes area to New England, the Maritimes and in the southern Appalachians. The green comma mainly occurs in forests, mountain woodlands, near streams and in canyons.
Females lay eggs on the upper surface of the leaves of the host plants. The solitary larvae feed on a wide range of hosts, especially on upland willow (Salix humilis), Betula lenta, alder, Rhododendron occidentale, and Ribes species. Other recorded plants are Nettles (Urtica species), Hops (Humulus species), Elm (Ulmus species) and Azalea (Rhododendron species). These butterflies have one generation per year (univoltines) and fly from May to September depending on the location. Adults overwinter until the following Spring.
