Hairy dragonfly

Take a walk on the Levels in late April or early May and you may be lucky enough to encounter one of our most beautiful insects, the Hairy Dragonfly (Brachytron pratense).

Until recently, this small dragonfly was rare in the UK, being found mostly on the south coast in Sussex and Kent, on the Somerset and Gwent Levels, and parts of Pembrokeshire. Over recent years it has benefited from milder winters and warmer summers and has spread across southern Britain. It is now found as far west as Ireland and has reached the west coast of Scotland.

Hairy Dragonflies are aptly named (C Harris)

The Hairy Dragonfly is aptly named. Males have a noticeably downy thorax (the middle section of the body), while females also have a hairy abdomen. Males and females are relatively easy to tell apart; males have pairs of blue spots along the abdomen, two green stripes on the top of the thorax, and striking blue eyes; females have pairs of yellow spots along the abdomen and brown eyes.

Hairy Dragonflies belong to a group called the ‘hawkers’, which, true to their name, spend much of their time as adults on the wing (‘hawking’), patrolling a territory, feeding or looking for a mate. This group includes some of our largest dragonflies, such as the Emperor Dragonfly, Brown Hawker and Southern Hawker. Hairy Dragonflies are the smallest members of the group.

The Levels has long been a stronghold for this species, as they favour areas with unpolluted, still or slow-flowing water with lots of natural vegetation. They are often associated with grazing marshes, but can also be found along canals and slow-flowing rivers, flooded gravel pits and lakes.

Hairy Dragonflies are one of the first species to emerge and adults can usually be seen from end of April through to early July.
