Overview

This species has undergone an extremely steep decline nationally and is also in danger in its Cumbria ‘hot-spot.’ It is found in LIMESTONE GRASSLAND where there is a mosaic of Bracken and herb rich grassland. It is also found in LIMESTONE WOODLANDS where it relies on freshly coppiced woodlands but this type of management is now rarely carried out due to unfavourable economics. Cumbria Branch are active in managing several woodlands to try to recreate the right breeding conditions but it is an uphill struggle as the decline in both habitat condition and colonies has gone so far. With help and encouragement from Cumbria Branch, Butterfly Conservation nationally have recently raised a substantial amount of Grant Aid over a four year period to manage more woodlands in the Morecambe Bay area. That period started in April 2008 and work has now commenced in the first few woodlands. Hopefully we will not be too late.

Where to look

Limestone grassland and Broadleaved woodlands where there are wide rides and/or freshly cleared/coppiced areas annually. Clearings with low patchy bracken are used as a warm micro-climate for egg laying. The best site is Gait Barrows NNR SD 482 773 to the west of Arnside, (a visitor permit should be obtained from Natural England).

When to look

Early May to late June.
