Scientific name: Argynnis adippe
Orange and black wings and fast flight distinguish this large butterfly from most others.
This large, powerful butterfly is usually seen flying swiftly over the tops of bracken or low vegetation in woodland clearings. In flight, the males are almost impossible to separate from those of the Dark Green Fritillary, which often share the same habitats. However, both species frequently visit flowers such as thistles and Bramble where it is possible to see their distinctive underside wing markings. The Dark Green lacks the orange ringed 'pearls' on the underside of the hindwing.
The High Brown Fritillary was once widespread in England and Wales but since the 1950s has undergone a dramatic decline. It is now reduced to around 50 sites where conservationists are working to save it from extinction.
