Libellula depressa, the broad-bodied chaser is one of the most common dragonflies in Europe and central Asia. It is very distinctive with a very broad flattened abdomen, four wing patches and, in the male, the abdomen becomes pruinose blue.
This insect is around 39–48 mm in length, with both the male and the female having a broad, flattened abdomen which is brown with yellow patches down the sides. In the male, the abdomen develops a blue pruinosity that covers the brown colour. Both fore and hind wings have a dark patch at the base. Both the male and female have broad antehumeral stripes. The average wingspan is approximately 70 mm. L. depressa is very distinctive and is not easily confused with any other dragonflies in the region.
L. depressa is found in central and southern Europe, central Asia and the Middle East. Its range extends northwards throughout England and Wales and into southern Scotland, southern Sweden and southern Finland. and it occurs on some Mediterranean islands including Corsica, Sardinia, Sicily, and Menorca. Historically its range did not extend into Scotland, but it has colonised north there in recent decades... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Broad-Bodied Chaser is recorded against all the insects logged in Pyrénées National Park (70 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.
