Comma

Polygonia c-album has a wingspan of about 45 millimetres (1.8 in).[1] The underside of the wings of this butterfly are a dull brown colour, with a small white 'C' shaped marking resembling a comma (hence the common name).The wings have a distinctive ragged edge, apparently a cryptic form as the butterfly resembles a fallen leaf. The species survives the winter in the adult stage, and adults are of two forms. The form that overwinters before reproducing has dark undersides of the wings, resembling a dead leaf, a perfect camouflage throughout the winter.The majority of the offspring have this dark form.
