Rare
Under 5% of wildlife watchers report a Variable Chafer sighting in Vienna on a given day, based on 15 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
In that month about 10% of wildlife watchers report a Variable Chafer in Vienna on a given day, against under 5% in August to June, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Variable Chafer sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Variable Chafer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Scarabaeidae
The closest relatives of the Variable Chafer that you can see in Vienna (family Scarabaeidae, Scarabs) are Mediterranean Spotted Chafer (about 30%), European Rose Chafer (about 20%) and Valgus hemipterus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Variable Chafer is recorded against all the insects logged in Vienna (15 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.
