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 →

With luck
About 10% of wildlife watchers report a Dark Sailor Beetle sighting in Wadden Sea National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 818 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.
May
In that month about 30% of wildlife watchers report a Dark Sailor Beetle in Wadden Sea National Park on a given day, against under 5% in July to April, the lowest months. That is one of Wadden Sea National Park's driest months, with about 45 mm of rain against 140 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dark Sailor 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.
Yes
Of the 3 parks where we can rate Dark Sailor Beetle sightings, Wadden Sea National Park has the highest daily chance: about 10%. Next come Bavarian Forest National Park (Germany, about 10%) and Pyrénées National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Dark Sailor Beetle is recorded against all the insects logged in Wadden Sea National Park (66 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.
