Agrion jouvencelle
(Coenagrion puella)

The Azure Bluet has a fairly long and slender build. This black-and-blue or - in the case of some females - black-and-green damselfly is probably the commonest and most widely distributed of all European Bluet species, extending its range from Southern Scandinavia all the way down to the Mediterranean. Coenagrion puella's main distinguishing features include its thin but uninterrupted antehumeral stripe, the U-shaped mark on the male's S2, and the long, thin lines which run along the sides of the male's abdomen. However, the Azure Bluet can easily be confused with the less common Variable Bluet (Coenagrion pulchellum).
