Overview

Clubiona trivialis is a small reddish brown spider with holarctic distribution. It is found in exposed places on low vegetation. Adults can be found throughout the year.

Clubiona trivialis faces significant threats from habitat degradation and fragmentation due to agricultural intensification and urban development across its range. The species' dependence on specific microhabitat conditions makes it particularly vulnerable to environmental changes, while pesticide use in agricultural areas poses additional risks to local populations.
