Collared pedunculate ground beetle

The Collared Pedunculate Ground Beetle, known scientifically as <em>Clivina collaris</em>, is a ground beetle belonging to the family Carabidae, one of the largest and most diverse families of beetles. <em>Clivina collaris</em> is a member of a group of fossorial ground beetles adapted for burrowing in soil and substrate. The species typically inhabits terrestrial and freshwater-associated environments, including riverbanks, muddy margins, and damp soils. It is reported to occur in Belgium, Canada, Denmark, Norway, and Sweden, suggesting a broad distribution across northern and temperate regions. Ground beetles of the genus Clivina are generally predatory or omnivorous, feeding on other invertebrates and organic matter within the soil. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Pedunculate Ground Beetle is currently assessed as Least Concern on the IUCN Red List.
