The Wall Brown is a medium-sized butterfly which is on the wing in two or three broods, between the middle of April and the end of October. It is a widespread, but declining, butterfly of hot, sunny places such as open grassland, sand dunes and rocky foreshores, disused quarries and railway cuttings, and even gardens. Caterpillars feed on a variety of grasses including False Broom and Tor-grass.
How to identify
The Wall Brown is mainly pale orange with greyish-brown markings and black eyespots. The best way to identify the 'brown' butterflies is by looking at the eyespots on their wings. The combination of orange and brown markings, together with one large eyespot on the forewing and four smaller eyespots on the hindwing, is unique to the Wall Brown.
Where to find it
A scarce butterfly of hot, sunny places in England, Wales, Northern Ireland and southern Scotland, particularly around the coast.

How can people help
The Wall Brown has been in serious decline across the inland parts of its range during recent years and is now a rare butterfly away from the coast. It relies on sensitive grassland, moor and dune habitats that are disappearing from our countryside. However, The Wildlife Trusts are working closely with farmers, landowners and developers to promote wildlife-friendly practices. 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.
