Brown Hairstreak

Thecla betulae


Brown Hairstreaks belong to the family Lycaenidae. They are decidedly elusive, but with determination and luck they can be discovered, but usually it's just a chance encounter. Male Brown Hairstreaks take their first flight to an assembly point - usually at the top of the tallest ash tree in the vicinity. (In the absence of ash trees, sycamore, oak and other species are sometimes used.) The males spend most of their lives high up in these so called "master trees", where they feed on aphid secretions which coat the buds and leaves. Females can sometimes be seen resting on leaves lower down or flying around the Blackthorn bushes looking for places to lay their eggs.


Usually seen in a woodland thicket nearby or containing their host plants.
