Rare
Under 5% of wildlife watchers report a Clay Fan-Foot sighting in Prague on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 281st 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 30%, if each day is a fresh chance.
June–July and September
In those months about 10% of wildlife watchers report a Clay Fan-Foot in Prague on a given day, against under 5% in August and October–May, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Clay Fan-Foot sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 cities where we can rate Clay Fan-Foot sightings, Prague has the highest daily chance: under 5%. Next come Berlin (Germany, under 5%) and Vienna (Austria, under 5%).

The closest relatives of the Clay Fan-Foot that you can see in Prague (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Jersey Tiger (about 10%), Burnet Companion (about 10%) and Spongy Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Clay Fan-Foot is recorded against all the insects logged in Prague (19 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.
