About

The pearl-bordered fritillary is a striking orange and black butterfly, often seen flying close to the ground along sunny woodland rides or feeding on spring flowers such as common dog-violet.  Pearl-bordered fritillaries lay their eggs singularly in bracken or leaf litter close to violets, the foodplant of the caterpillars which emerge in late June. 

How to identify

The pearl-bordered fritillary is an orange butterfly with black marks on the upperside of the wings. The underside have black and silver markings along with a row of white "pearls" along the outer edge of the wing which give the species its name. Can be confused with the small pearl-bordered fritillary which has a full row of "pearls" along the middle of the underside of its wing.

How can people help

The Wildlife Trusts manage many grassland and woodland habitats sympathetically for the benefit of all kinds of butterflies, including the pearl-bordered fritillary. Managing rides so they are open and sunny with coppice and flower rich grassy margins helps provide the ideal habitat for manay invertebrates which, in turn, support larger animals. By volunteering for your local Trust you can help too and you'll make new friends and learn new skills along the way.
