Enallagma cyathigerum Coenagrionidae Common Blue Damselfly

Biology male female Irish distribution

Enallagma cyathigerum

Widespread and common. Adults can be seen from May to the end of August. A common species, typically of lakes, especially deep open sites. Absent from small shallow pools such as those found on cutover bogs, though wandering adults will occur on these. It has been recorded at greater altitude than most other damselflies.

This species is similar to the Azure Damselfly, the Variable Damselfly and the Irish Damselfly but can be distinguished by the presence of a single stripe on the side of the thorax (visible in the photographs), the shape of the marking on segment 2 and by the shape of the pronotum.
