Heath fritillary

The rare heath fritillary was on the brink of extinction in the 1970s, but conservation action turned its fortunes around. It is still confined to a small number of sites in the south of England, however.

Ynghylch

The heath fritillary is a rare butterfly that is restricted to a few key habitats: primarily, coppiced woodland or sheltered heathland where it can be seen flying close to the ground in a distinctive flutter-and-glide pattern. It is confined to a small number of sites in Somerset, Devon, Cornwall and Kent, and has also been reintroduced into sites in Essex. Although very local in its distribution, this butterfly can be seen in large numbers in good years. It forms discrete colonies and rarely strays from its main breeding grounds.

Sut i'w hadnabod

The heath fritillary is variable in terms of both the colour and the pattern of the wings, but it mostly displays a dusky, orange-and-brown chequered pattern.
