With luck
About 10% of wildlife watchers report a Broad Scarlet sighting in Vienna on a given day, based on 128 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 1406 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.
July
In that month about 20% of wildlife watchers report a Broad Scarlet in Vienna on a given day, against under 5% in September to May, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Broad Scarlet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
31st of 38
Of the 38 cities where we can rate Broad Scarlet sightings, Vienna ranks 31st at about 10%. The best odds are in Antananarivo (Madagascar, about 50%), Ouagadougou (Burkina Faso, about 40%) and Antalya (Turkey, about 40%).
Same family: Libellulidae
The closest relatives of the Broad Scarlet that you can see in Vienna (family Libellulidae, Skimmers) are Ruddy Darter (about 10%), Common Darter (about 10%) and Black-Tailed Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Broad Scarlet is recorded against all the insects logged in Vienna (128 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.
