Rare
Under 5% of wildlife watchers report a Summer Rhizotrogus sighting in Vienna on a given day, based on 39 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.
April and May
In those months about 10% of wildlife watchers report a Summer Rhizotrogus in Vienna on a given day, against under 5% in June to March, the lowest months.

Across all the parks we cover, that three-hour window holds the most Summer Rhizotrogus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Summer Rhizotrogus is recorded against all the insects logged in Vienna (39 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.
