The golden-ringed dragonfly is a very large dragonfly which is on the wing from May to September. It is a dragonfly of small, acidic streams in moorland and heathland and may be found away from its breeding sites. The female of this species is the UK’s longest dragonfly because of her long ovipositor. Golden-ringed dragonflies are voracious predators, feeding on large insects such as damselflies, other dragonflies, wasps, beetles and bumblebees. They are fast, agile and powerful flyers.
