Pearl-bordered Fritillary

Photographed back in May, a Pearl-bordered Fritillary in Gloucstershire. This butterfly was once very widespread but has declined rapidly in recent decades, and is now highly threatened in England and Wales. It flies close to the ground, stopping regularly to feed on spring flowers such as Bugle. It can be distinguished from the Small Pearl-bordered Fritillary by the two large silver 'pearls' and row of seven outer 'pearls' on the underside hind wing, and also the red (as opposed to black) chevrons around the outer pearls and the small central spot on the hind wing.
