Cantharis fusca, the dark soldier beetle, is a species of soldier beetle. Cantharis fusca reaches a length of 10–15 millimetres (0.39–0.59 in). Except for parts of the head and thorax, which are red or orange, this species is completely black. The body is flat and long, with weak exoskeleton. These beetles have long feathery antennae, and comparatively long legs.
This species is common in large parts of Europe, and lives in bushes, edges of forests, and meadows. They hunt for small insects. The larvae have black hairs, and also eat small insects. They are very cold-resistant, and can be seen crawling on the snow in winter. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dark Sailor Beetle is recorded against all the insects logged in Pyrénées National Park (8 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.
