The white-legged damselfly or blue featherleg (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range. Platycnemis pennipes is about 32 millimetres (1.3 in) long. Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata.
The male has a blue abdomen that is often pale and usually has a greenish thorax. The female is a very pale yellow-green colour with black markings. This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation. it has been recorded in tidal rivers and the larvae seem well able to tolerate brackish water. It also occurs in muddy streams but is rare in lakes or ponds of any sort. In north-west Europe, it is mostly confined to flowing waters.
The males are very territorial and use their enlarged legs to impress other individuals. Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating... Wikipedia →

Possible
About 30% of wildlife watchers report a Blue Featherleg sighting in Kiskunság National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 95 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
May and June
In those months about 50% of wildlife watchers report a Blue Featherleg in Kiskunság National Park on a given day, against under 5% in March–April and July–October, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Blue Featherleg 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 8 parks where we can rate Blue Featherleg sightings, Kiskunság National Park has the highest daily chance: about 30%. Next come Plitvice Lakes National Park (Croatia, about 30%) and Biebrza National Park (Poland, about 30%).
Same order: Odonata

GBIF citizen-science records
It is estimated from how often the Blue Featherleg is recorded against all the insects logged in Kiskunság 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.
