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

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 →

Rare
Under 5% of wildlife watchers report a Eurasian Bee Beetle sighting in Saint Petersburg on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 155th most-seen of the 448 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 July
In those months about 10% of wildlife watchers report a Eurasian Bee Beetle in Saint Petersburg on a given day, against under 5% in August to May, the lowest months. Those are among Saint Petersburg's wettest months, with about 95 mm of rain a month against 40 mm in February.
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.
8th of 8
Of the 8 cities where we can rate Eurasian Bee Beetle sightings, Saint Petersburg ranks 8th at under 5%. The best odds are in Helsinki (Finland, about 10%), Nizhny Novgorod (Russia, about 10%) and Novosibirsk (Russia, about 10%).

GBIF citizen-science records
It is estimated from how often the Eurasian Bee Beetle is recorded against all the insects logged in Saint Petersburg (18 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.
