Green Comma (Polygonia faunus) lives in moist woodland edges across North America. It feeds on urtica and hops.
Fascinating facts about the Green Comma
- From the taiga of central Alaska down to the forests of central California and northern New Mexico, the green comma stitches together a massive swath of North America. It also threads through the Great Lakes, reaches the Atlantic seaboard of New England and the Maritimes, and climbs into the southern Appalachian mountains. Preferring forests, mountain woodlands, stream corridors and canyon walls, it lives where trees and water meet, showing how a single butterfly can link distant, cool habitats across a continent.
- Scientists sometimes split the green comma into five named subspecies, smythi, faunus, articus, rusticus and hylas, because the underside colour and the region where each lives differ. Yet most lepidopterists treat these forms as regional variants rather than separate species.
- A female green comma lays her eggs on the upper side of host-plant leaves, then a solitary larva hatches and feeds through the summer. The species produces only one generation each year, with adults on the wing from May through September depending on latitude, and the adults spend the winter in a dormant state, re-emerging in spring to start the cycle again.
- A green comma can span up to 64 mm across. The underside is a muted grey-brown, but the outer half brightens with greenish, lichen-mimicking spots that hide a tiny L- or C-shaped silver mark in the middle of the hindwing.
- Green comma caterpillars are dietary generalists, munching on a menu that includes upland willow, sweet birch, alder, western rhododendron and various Ribes shrubs. They also accept nettles, hops, elm and other azaleas when those plants are nearby.
