The scarce chaser (Libellula fulva) is a species of dragonfly. The adult male has a bright blue abdomen with patches of black, while the adult female and juvenile male each have a bright orange abdomen. It is about 45 mm in length with an average wingspan of 74 mm. It is distributed throughout Europe. This dragonfly is considered a species of special concern in Great Britain due to loss of its specific ideal habitat.
This species lives on floodplains and marshes with dense, abundant vegetation, and females deposit their eggs in slow-current streams. Once deposited by the female, the eggs lie embedded in the mud of the riverbed and the larvae develop underwater for usually two years. Adults live from May to August, during which time they mate and lay eggs.

With luck
About 10% of wildlife watchers report a Scarce Chaser sighting in Kyiv on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 753 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.
June
In that month about 20% of wildlife watchers report a Scarce Chaser in Kyiv on a given day, against under 5% in August to April, the lowest months. That is one of Kyiv's wettest months, with about 75 mm of rain against 40 mm in April.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Scarce Chaser sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 13
Of the 13 cities where we can rate Scarce Chaser sightings, Kyiv ranks 5th at about 10%. The best odds are in Brussels (Belgium, about 20%), Kharkiv (Ukraine, about 10%) and Rostov-on-Don (Russia, about 10%).
GBIF citizen-science records
It is estimated from how often the Scarce Chaser is recorded against all the insects logged in Kyiv (34 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.
