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 →

Rare
Under 5% of wildlife watchers report a Goblet-Marked Damselfly sighting in Prague on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 647th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Goblet-Marked Damselfly in Prague on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Goblet-Marked Damselfly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 cities where we can rate Goblet-Marked Damselfly sightings, Prague ranks 6th at under 5%. The best odds are in Lyon (France, about 10%), Paris (France, about 10%) and Essen (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Goblet-Marked Damselfly is recorded against all the insects logged in Prague (6 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.
