Theridion familiare

Local name: hålklotspindel

Unknown

Overview

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

Theridion familiare faces significant pressure from habitat degradation in its specialized microhabitats, particularly the loss of old-growth forest structures that provide the specific bark crevices and hollow spaces this species requires. Urban development and intensive forestry practices have reduced the availability of suitable nesting sites, while climate change may be altering the microclimatic conditions essential for this spider's survival and reproduction.

Threat summary

Habitat

This small theridiid spider inhabits bark crevices, hollow tree spaces, and similar protected microhabitats in mature forests. It shows a preference for older woodland areas where complex bark structures and stable microclimatic conditions provide suitable nesting and hunting grounds.
