Araeoncus crassiceps

Unknown

Overview

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

Araeoncus crassiceps faces severe habitat degradation from intensive forestry practices and agricultural expansion across its limited Scandinavian range. The species' dependence on old-growth forest floor microhabitats makes it particularly vulnerable to logging operations that alter soil moisture and leaf litter composition. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate moisture balance required for this ground-dwelling spider's survival.

Threat summary

Habitat

This small spider inhabits the forest floor of mature deciduous and mixed forests, particularly favoring areas with deep leaf litter and stable moisture conditions. It is typically found in undisturbed woodland environments with rich organic soil layers that support its prey base of small invertebrates.

Why is skovledderkopp classified as Endangered?
skovledderkopp 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. Araeoncus crassiceps faces severe habitat degradation from intensive forestry practices and agricultural expansion across its limited Scandinavian range. The species' dependence on old-growth forest floor microhabitats makes it particularly vulnerable to logging operations that alter soil moisture and leaf litter composition. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate moisture balance required for this ground-dwelling spider's survival.
Where does skovledderkopp live?
skovledderkopp occurs in Åland Islands, Austria, Belgium, China, Denmark, and Estonia (plus 14 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to skovledderkopp?
The main threats to skovledderkopp are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
