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. Size and Family - Family –
