Allomengea vidua

Local name: småfuktmattevever

Unknown

Overview

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

Allomengea vidua faces significant pressure from habitat degradation in its specialized wetland environments. The species is particularly vulnerable to changes in water quality and hydrological patterns that affect the moss and vegetation layers where it constructs its webs. Agricultural runoff and urban development near wetland margins have reduced the quality of suitable microhabitats, while climate-induced changes to precipitation patterns threaten the delicate moisture balance these spiders require.

Threat summary

Habitat

This small sheet-web spider inhabits wet moss layers and low vegetation in marshes, fens, and boggy areas throughout northern Europe. It requires consistently moist microhabitats with dense moss coverage where it can construct its characteristic horizontal sheet webs close to the ground surface.
