Overview

A small silvery blue butterfly which, unlike further south, usually has only a single brood in Cumbria. It is usually seen fluttering around Holly trees.


Where to look

The butterfly is found in woodland clearings, churchyards and hedgerows where Holly is growing. Although the distribution is widespread in Cumbria it is not commonly seen other than in the south of the county. Township Plantation (The Howe) is usually a good site, SD 452884.


When to look

Its flight period is from early April to mid-June peaking in late April.
