Named after the white comma mark on its underside, the comma is most recognisable by its ragged wing edges. Look out for it in parks and gardens on warm days all year round. Comma Facts: • An early alternative name was 'Jagged wing'd Comma' after its ragged wings. • The comma is one of the few species to have expanded its range considerably in the last few decades - this is thought to be due to warmer weather and a change in primary larval foodplant from hops to more common stinging nettles and elm. • Both sexes have a brighter adult form, known as hutchinsoni, formed by the earliest spring caterpillars.
