Bathyphantes setiger

Local name: stråflommattevever

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Bathyphantes setiger faces severe habitat degradation from agricultural intensification and urban development across its limited Scandinavian range. The species' specialized requirements for undisturbed moss layers and specific moisture conditions make it particularly vulnerable to land-use changes. Climate change poses an additional threat by altering the delicate microhabitat conditions this spider depends on for survival.

Threat summary

Habitat

This small spider inhabits undisturbed moss layers in boreal forests and wetland margins, requiring specific moisture and temperature conditions. It is typically found in pristine Sphagnum moss communities and similar bryophyte-rich microhabitats across Scandinavia.
