What dragonfly have I got in my pond?
The British Dragonfly Society website has a list of all the species of dragonfly found in the UK. They also have a list of frequently asked questions which provide more useful information.
What is the difference between a dragonfly and a damselfly?
A damselfly is smaller than a dragonfly and when at rest they hold their wings along the length of their abdomen. A damselfly's eyes are also always separate.
In contrast when a dragonfly is at rest it holds its wings at right angles from its body and it has large eyes that are usually touching.
