Trichodes apiarius is a beetle species of checkered beetles belonging to the family Cleridae, subfamily Clerinae. It is found in most of Europe, in the eastern Palearctic realm, and in North Africa. The adult is a hairy, small beetle with shining blue or black head and scutellum. The elongated elytra (wing cases) are bright red with black bands. This species can easily be distinguished from Trichodes alvearius for the black terminal band reaching the apex of the elytra. Adults grow up to 9–16 millimetres (0.35–0.63 in) and can be encountered from May through June on the flowers, mainly Apiaceae, feeding on the pollen. They also actively hunt small insects.
The larvae are parasites of bees (hence the name “apiarius”), as the adults lay the eggs in the nests of solitary bees (Osmia and Megachile species) or in hives of honey bees, eating larvae and nymphs. Wikipedia →

With luck
About 10% of wildlife watchers report a Bee-Eating Beetle sighting in Prague on a given day, based on 81 verified sightings from GBIF citizen-science data. It is the 67th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Bee-Eating Beetle in Prague on a given day, against under 5% in September to May, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Bee-Eating 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.
6th of 20
Of the 20 cities where we can rate Bee-Eating Beetle sightings, Prague ranks 6th at about 10%. The best odds are in Budapest (Hungary, about 20%), Vienna (Austria, about 10%) and Kharkiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Bee-Eating Beetle is recorded against all the insects logged in Prague (81 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.
