Authority
The species was first described by Victor Motschulsky in 1844.
Description
Dyschirius ferrugineus is a small ground beetle, typically measuring 3–5 mm in length. The species exhibits a reddish‑brown (ferruginous) coloration, which gives it its specific epithet “ferrugineus.” Like other members of the genus, it possesses a streamlined body adapted for digging, with pronounced mandibles and a set of elongated forelegs. The elytra are smooth with faint punctate striae.
Distribution
The species is primarily Palearctic. Documented records include:
- Central and Eastern Europe (e.g., Poland, Ukraine, and the Baltic states)
- Extending eastward into Siberia, Russia
Habitat
Dyschirius ferrugineus inhabits moist, sandy or loamy soils, often in riverine floodplains, wet meadows, and the margins of lakes and ponds. It is a nocturnal predator, feeding on small invertebrates such as springtails and other soil-dwelling arthropods.
Behavior and Ecology
- Activity: Primarily nocturnal; adults are ground‑active and are attracted to light sources.
- Life cycle: Like other Carabidae, it undergoes complete metamorphosis (egg → larva → pupa → adult). Specific details of its larval development are not extensively documented.
- Ecological role: As a predator of soil microfauna, it contributes to the regulation of invertebrate populations and participates in nutrient cycling within its habitat.
Conservation Status
There are no specific assessments of Dyschirius ferrugineus on the IUCN Red List. Its wide distribution and occurrence in various habitats suggest it is not currently considered threatened, though local populations may be affected by habitat loss, wetland drainage, and pollution.
Research and Cataloguing
The species is listed in several entomological catalogues and databases, such as:
- Catalogue of Life
