Description

Wing span: 39 - 49mm

The Glanville Fritillary is named after Eleanor Glanville, a 17th century lepidopterist who discovered it in Lincolnshire.

In Britain it is found almost exclusively on the south coast of the Isle of Wight, although there are two sites known on the mainland. It is widely found in western and central Europe, and southern Scandinavia.

This butterfly lives on undercliffs and the steep eroding slopes of coastal river valleys (chines). These slopes are warm and have a regular supply of the plantains on which the larvae feed.

The flight period is from mid-May to the end of June. In good years there may be a partial second generation in August. The larva is the overwintering stage.

The primary larval footplant is Ribwort Plaintain (Plantago lanceolata).

Adults often take nectar from Knapweeds, Thrift and Birds-foot Trefoil.

Adults have a rapid flight, interspersed with gliding. Females are fairly mobile and have been found several miles from their breeding site.

This species has Endangered status on the UK list.
