The marking on the second segment of the abdomen is U-shaped, separated from the segment's narrow terminal black band; this distinguishes it from the variable damselfly Coenagrion pulchellum where the U-shape is joined to the terminal band with a black line.
Segments three to five are blue with broader black terminal bands, lacking the forward-pointing projection the upper surface which adult male common blue damselfly has. Segment six has a similar pattern but with more restricted blue and a broader area of black, and segment seven is mostly black, with just a narrow blue area at the base.

Possible
About 20% of wildlife watchers report an Azure Damselfly sighting in Snowdonia National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 387 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report an Azure Damselfly in Snowdonia National Park on a given day, against under 5% in September to April, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Azure Damselfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 10
Of the 10 parks where we can rate Azure Damselfly sightings, Snowdonia National Park ranks 3rd at about 20%. The best odds are in Plitvice Lakes National Park (Croatia, about 30%) and Biebrza National Park (Poland, about 30%).
Same family: Coenagrionidae
The closest relatives of the Azure Damselfly that you can see in Snowdonia National Park (family Coenagrionidae, Narrow-winged Damselflies) are Large Red Damselfly (about 30%), Common Blue Damselfly (about 20%) and Small Red Damselfly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Azure Damselfly is recorded against all the insects logged in Snowdonia National Park (35 verified sightings from 2019 to 2026), 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.
