Enallagma cyathigerum (common blue damselfly or common bluet) is a species found mainly between latitudes 40°N and 72°N; It is widely distributed in the Palearctic, common in all European countries (including Portugal, Spain, France, Great Britain, Ireland, Germany, Sweden, Norway, Finland, Poland, etc.) and in Asia in Turkey, Iran, Russia, and South Korea, and throughout Ontario in North America. The species reaches a length of 29–36 mm (1.1–1.4 in) with wings 18–20 mm (0.71–0.79 in) long. Damselflies are an important link between the health of the aquatic ecosystem and its response to climate change. The closely related Nearctic species Enallagma annexum (northern bluet) was at one time considered to be synonymous with it.
These damselflies inhabit freshwater bodies whose conditions range, they have been seen in acidic fens as well as eutrophic ponds. They have been considered one of the more sensitive insects in an aquatic setting. They are important within the trophic levels as they are an intermediate predator. They consume smaller larvae and they are preyed on by fish and larvae bigger than them.
The larvae prefer a habitat that has a more complex structure in the... Wikipedia →

Likely
About 50% of wildlife watchers report a Common Blue Damselfly sighting in Plitvice Lakes National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 51 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
June
In that month about 70% of wildlife watchers report a Common Blue Damselfly in Plitvice Lakes National Park on a given day, against under 5% in April and September, the lowest months. December has too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Blue 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.
Yes
Of the 14 parks where we can rate Common Blue Damselfly sightings, Plitvice Lakes National Park has the highest daily chance: about 50%. Next come Aigüestortes National Park (Spain, about 40%) and Mercantour National Park (France, about 30%). All parks ranked.
Same family: Coenagrionidae
The closest relatives of the Common Blue Damselfly that you can see in Plitvice Lakes National Park (family Coenagrionidae, Narrow-winged Damselflies) are Large Red Damselfly (about 30%) and Azure Damselfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Blue Damselfly is recorded against all the insects logged in Plitvice Lakes National Park (46 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.
