With luck
About 10% of wildlife watchers report a Summer Rhizotrogus sighting in Prague on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 216th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January and April–May
In those months about 10% of wildlife watchers report a Summer Rhizotrogus in Prague on a given day, against under 5% in February–March and June–December, 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 Prague (26 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.
