Leucorrhinia caudalis, also known as the lilypad whiteface or the dainty white-faced darter, is a species of dragonfly in the family Libellulidae. It is found in Europe. Its natural habitats are swamps and freshwater lakes. It is threatened by habitat loss.
The lilypad whiteface was described as Libellula caudalis by the German entomologist Toussaint von Charpentier in 1840. It is known in English as the lilypad whiteface or the dainty white-faced darter. The lilypad whiteface is a large, easy-to-identify species with a broad clubtail. Males are dark with white on the face, abdomen, and the ends of the wings.
The lilypad whiteface is a palearctic species with a range that stretches from central Siberia to western Europe. It is common in Scandinavia and the Baltics, as well as eastern Europe. It was historically threatened and localised in continental Europe, but is now well-established in the western and central parts of the continent and has an increasing population with a expanding range. Its distribution in southeastern Europe is scattered, but is expanding, with newly-established populations in countries such as Bosnia... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lilypad Whiteface sighting in Vienna on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1178th 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 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lilypad Whiteface in Vienna on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Lilypad Whiteface sightings, Vienna has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Lilypad Whiteface is recorded against all the insects logged in Vienna (9 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.
