The Silver-washed Fritillary is a large, pale orange butterfly, so-named for the silver streaks on its underside. Adults are on the wing throughout the summer from late June to the end of August. They live in large broad-leaved woodlands (especially Oak woodlands), and feed on flowers such as Bramble in sunny glades and rides. The caterpillars feed on violets, particularly Common Dog-violet.
How to identify
The Silver-washed Fritillary is pale orange with an intricate pattern of black spots and lines on the upper wings. The underside of the rear wing is washed lime green and pink, with silvery streaks running across it. Fritillaries are one of the trickier groups of butterflies to identify; the Silver-washed Fritillary can be distinguished from the other large fritillaries by the pattern on its underside. The male also has four, very broad, black stripes across the forewings.

How can people help
The Silver-washed Fritillary suffered declines in the 20th century but has been spreading in recent years. The Wildlife Trusts are working closely with farmers, landowners and developers to promote wildlife-friendly practices that benefit butterflies and other wildlife. We have a vision of a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.
