Robertus insignis
Local name: kärrfuktspindel
Overview
Robertus insignis, known as kärrfuktspindel, is a small theridiid spider species with a distinctive dark coloration and compact body structure. This specialized arachnid plays a crucial role as a predator of small invertebrates in its wetland ecosystem, helping maintain the delicate balance of its microhabitat food web.
Robertus insignis, the kärrfuktspindel, is critically endangered due to its extremely limited distribution in specific wetland habitats in Sweden. The species faces severe threats from habitat destruction through wetland drainage, climate change affecting moisture levels, and potential pollution of its specialized bog and fen environments.
Habitat
This spider inhabits the moist, moss-rich areas of bogs, fens, and marshy wetlands where it constructs its webs among sedges and other wetland vegetation. It requires consistently high humidity levels and the specific microclimate conditions found in undisturbed peat-based ecosystems.
