Polygonia

See text Polygonia (from Greek πολύς - polys, "many"[1] and γωνία - gōnia, "angle"[2]) is a genus of butterflies with a conspicuous white mark on the underside of each hindwing, hence the common name comma.

They also have conspicuous angular notches on the outer edges of their forewings, hence the other common name anglewing butterflies.

The related genus Nymphalis also includes some anglewing species; Polygonia is sometimes classified as a subgenus of Nymphalis.

[3] Many members of Polygonia hibernate as adults.
