Colias croceus, the clouded yellow, is a small butterfly of the family Pieridae, the yellows and whites. Colias croceus croceus Colias croceus f. deserticola (Verity, 1909) Colias croceus f. helice (Hübner) Colias croceus f. helicina (Oberthür, 1880)
Colias crocea f. mediterranea (Stauder, 1913) All of these forms are usually considered synonyms of Colias croceus. Colias croceus is one of the most widespread species in Europe. The common clouded yellow's breeding range is North Africa and southern Europe and eastwards through Turkey into the Middle East, but it occurs throughout much of Europe as a summer migrant, in good years individuals reaching Scandinavia. In Asia, its range extends into central Siberia in the north and barely into India in the south; it is not found in Central Asia.
This species is primarily an immigrant to the UK, originating from southern Europe and northern Africa. In the UK they can be seen on the south coast almost every year in varying numbers, and regularly breed there. Occurrence in the rest of the UK varies considerably from year to year, but they are increasingly observed as far north as Dumfries... Wikipedia →

With luck
About 10% of wildlife watchers report a Clouded Yellow sighting in Turin on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Clouded Yellow is recorded against all the insects logged in Turin (14 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.
