Modern records
This species has suffered similar losses to the small pearl-bordered fritillary but has undergone even more dramatic declines. It is now thought to be extinct in the county, which is quite a contrast to being ‘found in some plenty’ 200 years ago. This butterfly needs newly coppiced woodland areas to thrive and it likely suffered from a reduction in this traditional management practice.
