The Life of Animals | Polygonia C-Album | The Comma has a white marking on its underwings resembling a comma. The wings have a distinctive ragged edge, Apparently a cryptic form as the butterfly resembles a fallen leaf. The caterpillars are also cryptic, resembling a bird dropping. In the UK the larvae feed on hop, stinging nettles, elm, and black currants; in other parts of its distribution (eg, in Sweden) it also feeds on Sallow and birch.
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, whereas the form That develops directly to sexual maturation has colured lighter wing undersides.
