Common Blue Damselfly - Enallagma cyathigerum


A medium-small damselfly. It can be distinguished from other blue damselflies by the thick blue stripe on its thorax. The other common and similar damselfly, the Azure, has a much thinner stripe. With a little practice, it is relatively easy to pick out this difference in the field. Mature females have three colour forms: 'blue', 'brown' (which is often yellowish-orange) and typical (greenish). The males are a drab pink/purple when just emerged, taking a few days to become blue. However they can be distinguished from females by having solid blue on the bottom 2 abdominal segments.

Identification difficulty

It favours open water habitat such as large ponds, lakes, canals and rivers but adults can be found away from water in shady spots such as woodland rides.

When to see it

It flies from May through to September.

UK Status

Widespread and fairly common throughout Britain.
