Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 20 millimetres (3⁄4 in) long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.
Cetonia aurata should not be confused with the North American rose chafer, Macrodactylus subspinosus, or with the rarely seen noble chafer, Gnorimus nobilis, which is very similar to the rose chafer. One way to identify Cetonia aurata is to look at its scutellum; on the noble chafer the scutellum is an equilateral triangle, but on the rose chafer it is an isosceles triangle.
Rose chafers are capable of fast flight; they fly with their wing cases down. They feed on pollen, nectar, and flowers, especially roses. They can be found among roses on warm sunny days from May until June or July, and occasionally as late as September. Rose chafers are found in southern and central Europe and in the southern part of the United Kingdom, where... Wikipedia →

With luck
About 10% of wildlife watchers report a European Rose Chafer sighting in Minsk on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 196 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a European Rose Chafer in Minsk on a given day, against under 5% in October to April, the lowest months. That is one of Minsk's wettest months, with about 100 mm of rain against 45 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most European Rose Chafer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
21st of 36
Of the 36 cities where we can rate European Rose Chafer sightings, Minsk ranks 21st at about 10%. The best odds are in Kyiv (Ukraine, about 30%), Kharkiv (Ukraine, about 30%) and Paris (France, about 20%).
Same family: Scarabaeidae
The closest relatives of the European Rose Chafer that you can see in Minsk (family Scarabaeidae, Scarabs) are Summer Chafer (about 10%), Mediterranean Spotted Chafer (about 10%) and Common Cockchafer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Rose Chafer is recorded against all the insects logged in Minsk (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.
