The Golden-ringed Dragonfly, Cordulegaster boltonii, is a large, striking dragonfly and the longest British species,[1] the only one of its genus to be found in the United Kingdom.[2]

Identification[edit]

They are easily identified by their distinctive black and yellow stripes, which no other dragonfly in the United Kingdom has.[3] A very large species, males average 74 mm and the larger females 84 mm. Wingspan is up to 101 mm.[4]

Larvae[edit]

The female lays the eggs in shallow water. The hairy larvae live at the bottom of the water and are well camouflaged amongst the silt.[5] They emerge after about 2–5 years, and usually under the cover of darkness.

Behaviour[edit]

They are often seen flying leisurely over mountain streams or a river; they also occasionally show up at a pond. They are also typically seen flying over heath land. Their bright yellow and black stripes make them easy to identify, even from a fair distance away. They feed mainly on insects ranging from small prey such as midges to flies, butterflies and even bumblebees. This strikingly-coloured insect is incredibly aerobatic and they sometimes fly very high up into the sky.[6]
