Rhagonycha fulva, the common red soldier beetle, also misleadingly known as the bloodsucker beetle, and popularly known in England as the hogweed bonking beetle is a species of soldier beetle (Cantharidae).

Rhagonycha fulva measures 8–10 millimetres (0.31–0.39 in) in length. Its antennae are black, occasionally the first segment is orange. The head and pronotum are orange and shiny, with fine pubescence visible on the head. The shape of the pronotum is variable, but it narrows towards the head. The elytra cover the wings and most of the abdomen and are a dark shiny red, and terminate in a clearly visible black patch on the apical end – this is one of the key identifying features. The femora and tibiae are orange, but the tarsi are black; the third segment of the tarsi is simple rather than bilobed.
All soldier beetles are soft-bodied, resulting in the German name of this species as Roter Weichkäfer (meaning "red soft beetle"). This beetle is very common in Europe and Anatolia. Introduced to North America, it is well... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Red Soldier Beetle sighting in Vienna on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 351st most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Common Red Soldier Beetle in Vienna on a given day, against under 5% in August to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Common Red Soldier Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
45th of 45
Of the 45 cities where we can rate Common Red Soldier Beetle sightings, Vienna ranks 45th at about 10%. The best odds are in Liverpool (United Kingdom, about 30%), Manchester (United Kingdom, about 30%) and Helsinki (Finland, about 20%).
Same family: Cantharidae

GBIF citizen-science records
It is estimated from how often the Common Red Soldier Beetle is recorded against all the insects logged in Vienna (42 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.
