Holly Blue
Flight period: late April to end of August.
The Holly Blue is easily identified in early spring as it emerges well before other blue butterflies. It tends to fly high around bushes and trees whereas other grassland blues usually stay near ground level. It is the commonest blue butterfly found in parks and gardens where it congregates around Holly (in spring) and Ivy (in late summer).
The Holly Blue is widespread but undergoes large fluctuations in numbers from year to year. It has expanded northwards in recent years and has now colonised parts of north England and the extreme south of Scotland.
