Pearl-bordered Fritillary

Boloria euphrosyne (59.0140)

The Pearl-bordered Fritillary became extinct in Warwickshire in 1969. It was once thought to be abundant in the larger Woodlands of the region but had all but disappeared by the early 1960's

In 2012, the Pearl-bordered Fritillary appeared at Ryton Wood due to an un-sanctioned re-introduction. It has since established itself at Pagets Pool and parts of Ryton Wood and Ryton Wood Meadow Butterfly Conservation Reserve.

  • 1968: Oakley Wood - the last confirmed sighting of this species in Warwickshire
  • 1960: Four, possibly five at Bubbenhall Wood (Lesley Moore).

In the afternoon I went to Bubbenhall glade. Here I took four Pearl-bordered Fritillaryies (sic) and could have caught many more, being more about than usual.

Pleased to see four or five at Bubbenhall Wood, as I feared them to be extinct after the felling.
