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 →

With luck
About 10% of wildlife watchers report a Sulphur Beetle sighting in Kyiv on a given day, based on 82 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 753 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Sulphur Beetle in Kyiv on a given day, against under 5% in August–September and November–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.
2nd of 8
Of the 8 cities where we can rate Sulphur Beetle sightings, Kyiv ranks 2nd at about 10%. The best odds are in Berlin (Germany, about 20%).
Same family: Tenebrionidae
The closest relatives of the Sulphur Beetle that you can see in Kyiv (family Tenebrionidae, Darkling Beetles) are Diaperis boleti (about 10%), Opatrum sabulosum (about 10%) and Stenomax aeneus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sulphur Beetle is recorded against all the insects logged in Kyiv (82 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.
