Broscus cephalotes is a species of nocturnal, coastal ground beetle found throughout most of Europe. Its range spans from western Europe into western Siberia. The species was introduced recently (circa 1975) in the eastern areas of Canada and has spread farther south and west into the United States. As a member of the family Carabidae, Broscus cephalotes is generally considered beneficial to humans due to its predatory habits. Their varied diet often includes crop pests and other small organisms.
Broscus cephalotes has a dull black coloration, without any metallic hue, and it can be quite large: between 16 and 23 mm. The morphology of the beetle is similar to other beetles in its family. B. cephalotes is flightless and flatter than many other species of Carabidae, which helps it hide in close spaces (e.g. crevices under stones or under bark). Body shape and presence or absence of the ability of flight can provide clues to diet of beetles, but does not provide conclusive evidence. Although mouth-parts are a better indicator of the type of food consumed by the beetle, the best method of determining the diet of a beetle is gut dissection. The asymmetric mandibles... Wikipedia →

Rare
Under 5% of wildlife watchers report a Broscus cephalotes sighting in Wadden Sea National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 486th most-seen of the 818 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 August
In those months about 10% of wildlife watchers report a Broscus cephalotes in Wadden Sea National Park on a given day, against under 5% in July and September–May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Broscus cephalotes sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Wadden Sea National Park, in our data
Wadden Sea National Park is the only park on Wallace's Line with enough records to rate Broscus cephalotes sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Carabidae
The closest relatives of the Broscus cephalotes that you can see in Wadden Sea National Park (family Carabidae, Ground Beetles) are Northern Dune Tiger Beetle (about 10%), Dune Tiger Beetle (about 10%) and Granulated Ground Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Broscus cephalotes is recorded against all the insects logged in Wadden Sea National Park (10 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.
