Hairy Dragonfly

The hairy dragonfly is named for its hairy thorax, distinguishing it from other hawkers. It has a long, narrow pterostigma (the coloured, sclerotized patch on the outer region of each wing). The antehumeral stripes are usually thin and green. The hairy dragonfly has coupled, oval-shaped markings on its abdomen, blue on males and yellow on females. It is smaller than other species in the genus Aeshna. It is the United Kingdom's smallest hawker.

The hairy dragonfly lives in ponds, lakes, fens, ditches, and canals rich in vegetation. Some plants that grow there include the common club rush, common reed, great fen sedge, and true bulrush. This dragonfly requires open and sunny areas with dense vegetation for protection. Here they are able to feed on flying insects, shelter, and grow sexually mature. Although it is a common species, it is susceptible to uncongenial ditch management and poor water conditions. This is the reason the species disappeared for a few years, only to return recently. More so than its other relatives, the hairy dragonfly will only fly in sunshine and will hastily retreat if the sun happens to go in.

Like typical hawkers, the hairy dragonfly preys in mid-air on flying insects. It then carries its food to a suitable perch where it is able to eat and digest.
