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).

The femora and tibiae are orange, but the tarsi are black; the third segment of the tarsi is simple rather than bilobed.

GBIF citizen-science records
It is estimated from how often the Common Red Soldier Beetle is recorded against all the insects logged in Sierra de Guadarrama National Park (7 verified sightings from 2019 to 2026), 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.
