Overview

Britain's only entirely brown large dragonfly. The Brown Hawker is unmistakeable in flight — all other large hawkers have blue or green markings on a dark body, but the Brown Hawker is warm amber-brown throughout. In flight it looks orange-brown in sunlight, the wings themselves with an amber tint. It hawks over large areas including along hedgerows well away from water. A large, powerful dragonfly that patrols continuously.

Frequently Asked Questions

Why is the Brown Hawker amber-coloured?

The amber-brown colouration of the Brown Hawker is unusual among large dragonflies, most of which are blue-and-black or green-and-black. The function of the colouration is not fully understood but may provide better camouflage against autumn vegetation (when the species is most abundant). The amber-tinted wings are a particularly beautiful feature visible in sunlight.
