Ischnura pumilio
In 3 days ~20% in a week ~40%
The scarce blue-tailed damselfly or small bluetail (Ischnura pumilio) is a member of the damselfly family Coenagrionidae. The species occurs throughout Europe except in the north. To the east it occurs from Asia Minor to Siberia, to the south the range extends to Morocco, the Azores and Madeira. The typical male has a black abdomen with a bright blue spot on tail (segments 8 and 9). It is very similar to the blue-tailed damselfly, Ischnura elegans but on that species the blue spot is mostly on segment 8. Females undergo a change of colour as they mature. The immature female is bright orange, the aurantiaca phase, but matures to a greenish-brown. Wikipedia →

With luck
About 10% of wildlife watchers report a Scarce Blue-Tailed Damselfly sighting in Budapest on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 179th most-seen of the 404 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Scarce Blue-Tailed Damselfly in Budapest on a given day, against under 5% in September to April, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Scarce Blue-Tailed Damselfly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 4 cities where we can rate Scarce Blue-Tailed Damselfly sightings, Budapest has the highest daily chance: about 10%. Next come Milan (Italy, about 10%) and Lisbon (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Scarce Blue-Tailed Damselfly is recorded against all the insects logged in Budapest (14 verified sightings), 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.
