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 →

Likely
About 40% of wildlife watchers report a European Rose Chafer sighting in Triglav National Park on a given day, based on 121 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 260 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report a European Rose Chafer in Triglav National Park on a given day, against under 5% in March–April and October, the lowest months.
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.
Yes
Of the 14 parks where we can rate European Rose Chafer sightings, Triglav National Park has the highest daily chance: about 40%. Next come Białowieża National Park (Poland, about 30%) and Gauja National Park (Latvia, about 30%). All parks ranked.
Same family: Scarabaeidae
The closest relatives of the European Rose Chafer that you can see in Triglav National Park (family Scarabaeidae, Scarabs) are Eurasian Bee Beetle (about 30%), Mediterranean Spotted Chafer (about 20%) and Summer Chafer (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 Triglav National Park (121 verified sightings from 2019 to 2026), 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.
