Description

Wingspan: 86-106mm; Body length: 67-76mm
 
A large, inquisitive Hawker usually seen individually. The spots on segments 8-10 are joined, unlike other Hawkers. The ante-humeral stripes are broad and strongly coloured. The costa is dark and there is an elongated triangular mark on S2. The male has a pronounced 'waist' between S3 and S4, which is missing in the female.
 
The male is brightly marked on a dark background, usually apple green except for S8-10, which are pale blue. Occasionally, all pale blue marked individuals are seen. The female is brown with bright green markings. Immatures of both sexes are brown with pale yellow markings, and brown eyes.
 
The Southern Hawker's breeding habitat of small stagnant pools is favoured by few other dragonflies. It often feeds along woodland rides and clearings. it is most often seen in July and August, but can persist well into the autumn.
