Cheiracanthium pennyi

Unknown

Overview

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

Cheiracanthium pennyi faces severe habitat degradation from agricultural intensification and urban development across its limited Scandinavian range. The species' specialized microhabitat requirements make it particularly vulnerable to changes in vegetation structure and moisture levels. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate ecological balance this spider depends upon.

Threat summary

Habitat

This spider inhabits specialized microhabitats within Scandinavian grasslands and forest edges, requiring specific vegetation structures and moisture conditions. It typically occurs in areas with dense herbaceous vegetation that provides both hunting grounds and shelter from environmental extremes.
