How to identify
The broad, flattened body of the Broad-bodied chaser is distinctive and makes this dragonfly appear 'fat'. The male has a powder-blue body with yellow spots along the sides and a dark thorax; the female is greeny-brown. There are several medium-sized, pale blue dragonflies that can be confused. This species can be distinguished by the combination of its broad, blue body and chocolate-brown eyes.https://www.devonwildlifetrust.org/wildlife-explorer/invertebrates/dragonflies/broad-bodied-chaser

Devonshire Association Entomology Section The Entomology Section promotes the study and recording of insects and also spiders in the county.
Meetings, talks, exhibitions, publications and field trips are arranged annually across the county of Devon and are suitable for beginners and experienced alike. Field trips are usually held in association with other specialist groups with whom we maintain close links. We also meet with other sections to demonstrate, and learn, about the inter-relationships with other disciplines.
With at least ten specialists in different Orders within the insect class we cater for a wide range of interests. Some of our Recorders are national experts in their field and hence we are the major collective source of entomological expertise in the county.
