Cteniopus sulphureus, the sulphur beetle, is a species of comb-clawed beetles belonging to the family Tenebrionidae subfamily Alleculinae. These beetles are mainly present in Denmark, Finland, Slovenia, Italy and Sweden.
The adults grow up to 7–8 millimetres (0.28–0.31 in) long. Elytra are pale yellow, while head and pronotum are orange-yellow. The shape of the head is extended forward. These thermophilic beetles can mainly be encountered in sunny places on inflorescences of Apiaceae and Asteraceae species, especially Achillea species. Wikipedia →

Possible
About 20% of wildlife watchers report a Sulphur Beetle sighting in Berlin on a given day, based on 291 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 1065 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.
June and July
In those months about 40% of wildlife watchers report a Sulphur Beetle in Berlin on a given day, against under 5% in August to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Sulphur 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.
Yes
Of the 8 cities where we can rate Sulphur Beetle sightings, Berlin has the highest daily chance: about 20%. Next come Kyiv (Ukraine, about 10%) and Warsaw (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the Sulphur Beetle is recorded against all the insects logged in Berlin (291 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.
