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 →

Rare
Under 5% of wildlife watchers report a Variable Bluet sighting in Wadden Sea National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 422nd most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Variable Bluet in Wadden Sea National Park on a given day, against under 5% in July to April, the lowest months.
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.
4th of 4
Of the 4 parks where we can rate Variable Bluet sightings, Wadden Sea National Park ranks 4th at under 5%. The best odds are in Biebrza National Park (Poland, about 20%), 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 Wadden Sea National Park (12 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.
