Comma Butterfly (Polygonia c-album) - Identification & Ecology #1337852 (License: Personal Use)

This scientific illustration depicts the comma butterfly (Polygonia c-album), notable for its irregular, comma-shaped silver mark on the underside of the hindwing and vibrant orange patches on dark brown forewings. The wings are fully spread, revealing fine venation and subtle yellow-green shading near the body, typical of 19th-century entomological plates. The small numeral “1” suggests it’s part of a numbered series in a natural history publication.
