trommelwolfspin

Hygrolycosa rubrofasciata

Unknown

Overview

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

The trommelwolfspin faces severe habitat degradation from agricultural intensification and urban development across its limited European range. Wetland drainage and water pollution have eliminated many suitable breeding sites, while climate change is altering the hydrological patterns essential for this semi-aquatic spider's survival. The species' specialized habitat requirements and limited dispersal ability make population recovery extremely difficult once local extinctions occur.

Threat summary

Habitat

This semi-aquatic wolf spider inhabits the margins of wetlands, including marshes, pond edges, and slow-flowing streams with dense vegetation. It requires areas with fluctuating water levels and abundant prey, typically found in lowland regions with rich organic substrates.

Frequently asked questions

Why is trommelwolfspin classified as Vulnerable?
trommelwolfspin is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The trommelwolfspin faces severe habitat degradation from agricultural intensification and urban development across its limited European range. Wetland drainage and water pollution have eliminated many suitable breeding sites, while climate change is altering the hydrological patterns essential for this semi-aquatic spider's survival. The species' specialized habitat requirements and limited dispersal ability make population recovery extremely difficult once local extinctions occur.
Where does trommelwolfspin live?
trommelwolfspin occurs in Åland Islands, Austria, Belarus, Belgium, Czechia, and Denmark (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 trommelwolfspin?
The main threats to trommelwolfspin 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.
