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 →

Possible
About 20% of wildlife watchers report a Eurasian Bee Beetle sighting in Ecrins National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 251 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Eurasian Bee Beetle is recorded against all the insects logged in Ecrins National Park (29 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.
