The largest of the hawker dragonflies found in Britain, this is a common species in southern England and Wales.
Left: a female Emperor dragonfly laying eggs in mid summer.
The male (below) has a bright blue body, while the female, seen above laying eggs on emergent vegetation, has a greenish tinge, becoming gradually bluer when old.
Mainly seen over ponds, canals or slow-flowing streams, this beautiful insect flies for long periods without resting, which makes it a difficult dragonfly to study.
