Diacrisia sannio
In 3 days ~10% in a week ~20%
Diacrisia sannio, the clouded buff, is a moth of the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in the Palearctic realm from Ireland to Siberia. It is not found in North Africa. In the Russian Far East (Amur, Primorye, Sakhalin, Kunashir), eastern China, Korea, and Japan it is replaced by Diacrisia irene.
The wingspan is 35–50 mm. The forewing of the male is lemon yellow, and the hindwing is ivory yellow, both wings with a greyish red median spot and pink margin. In the female the body and wings are suffused with brownish red. In pallida Stgr., which occurs constantly in Central Asia and aberratively also in Europe, the black colour is reduced. In irene Butl. (now full species Diacrisia irene Butler, 1881), which occurs in Japan and locally also elsewhere in the Palearctic region, and is regarded by Matsumura as a separate species, the black colour is absent on the hindwing of the male and the median spot on the forewing is generally reduced.

Rare
Under 5% of wildlife watchers report a Clouded Buff sighting in Prague on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 406th 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.
June and August
In those months about 10% of wildlife watchers report a Clouded Buff in Prague on a given day, against under 5% in July and September–May, the lowest months. Those are among Prague's wettest months, with about 80 mm of rain a month against 30 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Clouded Buff sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Clouded Buff sightings, Prague has the highest daily chance: under 5%. Next come Vienna (Austria, under 5%) and Moscow (Russia, under 5%).
Same family: Erebidae
The closest relatives of the Clouded Buff 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 Clouded Buff is recorded against all the insects logged in Prague (13 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.
