Local name: knøttalvmattevever

Unknown

Overview

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

Maro minutus faces significant pressure from habitat degradation in its specialized moss and lichen microhabitats. Agricultural intensification and forestry practices that alter ground-layer vegetation structure pose the primary threats to this minute spider. Climate change may further impact the delicate moisture conditions required for the moss communities where this species thrives.

Threat summary

Habitat

This tiny spider inhabits moss and lichen communities in forest floors, particularly in coniferous and mixed woodlands. It requires stable moisture conditions and undisturbed ground-layer vegetation where it constructs minute sheet webs among moss stems.
