Coenagrion pulchellum
In 3 days ~60% in a week ~90%
The variable damselfly or variable bluet (Coenagrion pulchellum) is a European damselfly. Despite its name, it is not the only blue damselfly prone to variable patterning. Its behaviour is much like that of the azure damselfly; it usually stays close to vegetation. Immatures are often found in adjacent meadows or uncut grassy areas. Wikipedia →

Possible
About 20% of wildlife watchers report a Variable Bluet sighting in Biebrza National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 97 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Variable Bluet in Biebrza National Park on a given day, against under 5% in March–April and July–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 Variable Bluet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Variable Bluet sightings, Biebrza National Park has the highest daily chance: about 20%. Next come Kiskunság National Park (Hungary, about 20%) and Białowieża National Park (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the Variable Bluet is recorded against all the insects logged in Biebrza National Park (16 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.
