Trichius fasciatus, the Eurasian bee beetle, is a beetle species belonging to the family Scarabaeidae, subfamily Cetoniinae. Varieties include: Trichius fasciatus var. dubius Mulsant Trichius fasciatus var. interruptus Mulsant
This beetle is present in most of Europe and in the eastern Palearctic realm. It is often found in forest clearings in mountainous areas, but rarely in the lowlands. It lives mostly on flowers on forest meadows and forest edges.
Trichius fasciatus can reach a length of 9–12 millimetres (0.35–0.47 in). Head and pronotum are black, while the elytrae vary from light yellow to deep orange. They are crossed by a few black bands. The first black band reaches the scutellum.The sides of the chest and the back of the abdomen are covered with a yellow-orange or white pubescence. This makes it look a bit like a Bumblebee, giving it better protection from predators. Hence the popular name of "Bee beetle" for their genus.
In this species males and females can be easily distinguished based on the front legs. In the female (Encl. 3) the outer teeth are strong, typical for the digging legs. The first tarsus... Wikipedia →

With luck
About 10% of wildlife watchers report a Eurasian Bee Beetle sighting in Stockholm on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 73rd most-seen of the 202 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Eurasian Bee Beetle in Stockholm on a given day, against under 5% in September to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Eurasian Bee Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 8 cities where we can rate Eurasian Bee Beetle sightings, Stockholm ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Helsinki (Finland, about 10%), Nizhny Novgorod (Russia, about 10%) and Novosibirsk (Russia, about 10%).
Same family: Scarabaeidae
The closest relatives of the Eurasian Bee Beetle that you can see in Stockholm (family Scarabaeidae, Scarabs) are European Rose Chafer (about 10%) 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 Eurasian Bee Beetle is recorded against all the insects logged in Stockholm (11 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.
