The goblet-marked damselfly (Erythromma lindenii) is a medium-sized blue-and-black (or green-and-black) damselfly in the pond damselfly family (Coenagrionidae). It's a fairly common species in the South and West of Europe but is not found in the British Isles, Scandinavia and Eastern Europe. Erythromma lindenii was previously known as Coenagrion lindenii and Cercion lindenii. The goblet-marked damselfly is also known as the blue-eye. It's an easily recognized species, with its wide antehumeral stripes, narrow postocular spots, the male's very bright-blue eyes. He has very long and curved appendages, and the spear-shaped marks on S3-S6 of his abdomen.
It can also be found in Asia: Russian Federation and it is also found in Africa. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Goblet-Marked Damselfly is recorded against all the insects logged in Essen (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
