In 3 days ~10% in a week ~30%
Sympetrum meridionale, the southern darter, is a species of dragonfly belonging to the Skimmer family Libellulidae. The adults grow up to 35–40 millimetres (1.4–1.6 in) long. The wingspan reaches 52–60 millimetres (2.0–2.4 in).
The abdomen of adult males is orange-reddish, without black spots on segments. The sides of the thorax are yellowish-brown. The adult females are quite similar to males, but the background color is more yellow. The wings are hyaline, with yellow or pale brown pterostigma.
Their life cycle lasts two or three years. They can be encountered from May through mid October in the immediate vicinity of shallow, well vegetated still water, where the larvae develop. This species is present in most of southern Europe.

Rare
Under 5% of wildlife watchers report a Southern Darter sighting in Vienna on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 367th most-seen of the 1406 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.
June to September
In those months about 10% of wildlife watchers report a Southern Darter in Vienna on a given day, against under 5% in October to May, the lowest months. Those are among Vienna's wettest months, with about 85 mm of rain a month against 40 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Southern Darter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 9
Of the 9 cities where we can rate Southern Darter sightings, Vienna ranks 7th at under 5%. The best odds are in Rostov-on-Don (Russia, about 20%), Budapest (Hungary, about 10%) and Bucharest (Romania, about 10%).
Same genus: Sympetrum
The closest relatives of the Southern Darter that you can see in Vienna (genus Sympetrum, Meadowhawks) are Ruddy Darter (about 10%) and Common Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Darter is recorded against all the insects logged in Vienna (41 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.
