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.

What to look for

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.

Where to find

Restricted to parts of South West and South East England.
