Pyrochroa coccinea, commonly known as the Black-headed cardinal beetle, is a species of cardinal beetle in the family Pyrochroidae. It is found mainly in wooded areas and pastures throughout central Europe, including southern Great Britain. Similar to other species of ambrosia beetles, P. coccinea live and reproduce on wooden logs in early stages of decomposition. Larvae develop over the span of many years, with overlapping generations often inhabiting a single wooden territory. Adults, however, are short-lived and exist during a brief season. They typically show up in April, become more populous in May and early June, and become very rare in the remaining months.
In Europe, Pyrochroa coccinea is found in mainly the central regions but its presence also expands south to the Pyrenees, central Italy, and Greece; north to southern Scandinavia and the United Kingdom; and east to Ukraine, western Russia, and Kazakhstan.
Pyrochroa coccinea is widespread in southern England and is most commonly found in the southeastern regions. It is found more locally and sporadically in northern regions toward the Lake District and expands well into the Welsh Border Counties. This... Wikipedia →

With luck
About 10% of wildlife watchers report a Black-Headed Cardinal Beetle sighting in Vienna on a given day, based on 159 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 1406 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.
April and May
In those months about 20% of wildlife watchers report a Black-Headed Cardinal Beetle in Vienna on a given day, against under 5% in July to March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-Headed Cardinal 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.
Among the best
Of the 24 cities where we can rate Black-Headed Cardinal Beetle sightings, Vienna ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%), Warsaw (Poland, about 10%) and Berlin (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-Headed Cardinal Beetle is recorded against all the insects logged in Vienna (159 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.
