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 →

Rare
Under 5% of wildlife watchers report a Broad-Bodied Chaser sighting in Moscow on a given day, based on 106 verified sightings from GBIF citizen-science data. It is the 132nd most-seen of the 1111 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 to July
In those months about 10% of wildlife watchers report a Broad-Bodied Chaser in Moscow on a given day, against under 5% in August to April, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Broad-Bodied Chaser sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
24th of 28
Of the 28 cities where we can rate Broad-Bodied Chaser sightings, Moscow ranks 24th at under 5%. The best odds are in Birmingham (United Kingdom, about 10%), Leeds (United Kingdom, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Broad-Bodied Chaser is recorded against all the insects logged in Moscow (106 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.
