Agroeca dentigera

Local name: kärrmånspindel

Unknown

Overview

Agroeca dentigera is a small ground-dwelling spider species with a brownish coloration and distinctive dental-like projections on its chelicerae that give it its scientific name. This nocturnal hunter plays an important ecological role as both predator of small invertebrates and prey for larger arthropods and small vertebrates in its ecosystem.

Agroeca dentigera faces severe population declines primarily due to habitat loss and degradation of its specialized wetland environments. The species is particularly vulnerable to drainage of marshlands, agricultural intensification, and changes in water management practices that alter the moisture regimes of its preferred habitats.

Threat summary

Habitat

This spider inhabits the margins of marshes, bogs, and wet meadows, particularly favoring areas with dense sedge tussocks and moss layers that provide both hunting grounds and shelter. It requires consistently moist soil conditions and is typically found in areas subject to seasonal flooding or permanent high water tables.

Frequently asked questions

Why is kärrmånspindel classified as Endangered?
kärrmånspindel is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure.
