Purple Hairstreak (Favonius quercus)

This is one of the commonest hairstreaks in England, but because adults spend most of their lives in tree tops (especially Oaks), they are easy to overlook. However, the adults are occasionally seen basking at lower levels, on various small trees, shrubs and bracken. On Hartlebury Common they are to be found in the wooded areas of the common, in July and August.
