Rare
Under 5% of wildlife watchers report a Lesser Hornet Hoverfly sighting in Vienna on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 698th 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.
July and August
In those months about 10% of wildlife watchers report a Lesser Hornet Hoverfly in Vienna on a given day, against under 5% in September to June, 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 Lesser Hornet Hoverfly sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 19
Of the 19 cities where we can rate Lesser Hornet Hoverfly sightings, Vienna ranks 18th at under 5%. The best odds are in London (United Kingdom, about 20%), Birmingham (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Lesser Hornet Hoverfly is recorded against all the insects logged in Vienna (18 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.
