Purple Hairstreak

Quercusia quercus
Female, 10 August 1978 7 August 1983


The Purple Hairstreak is usually seen high up in Oak trees in woods, hedgerows, parks and gardens. It can sometimes be found seeking moisture closer to ground level, particularly in very dry summers.

Conservation Issues

Loss of hedgerow oaks could reduce its habitat, but oaks remain quite common throughout the county and abundant in places, so the species is not under threat.

Flight Period

Mainly from July to mid August.


The species occurs on oaks throughout the area, but it is often overlooked because of its habits. The map gives a misleading impression because of this.
