Rare
Under 5% of wildlife watchers report a Red-Headed Chestnut sighting in Prague on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 505th most-seen of the 724 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.
March and October
In those months about 10% of wildlife watchers report a Red-Headed Chestnut in Prague on a given day, against under 5% in April–September and November–February, the lowest months.

GBIF citizen-science records
It is estimated from how often the Red-Headed Chestnut is recorded against all the insects logged in Prague (8 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.
