Maro lehtineni

Unknown

Overview

Maro lehtineni is a minute sheet weaver spider endemic to northern European regions, characterized by its pale coloration and extremely small size of just 1-2mm. This cryptic arachnid plays a crucial role in controlling populations of springtails and other micro-arthropods in specialized moss and lichen communities.

Maro lehtineni faces severe population declines primarily due to habitat destruction from deforestation and agricultural expansion in its limited range. Climate change and habitat fragmentation further threaten the remaining populations of this endemic spider species.

Threat summary

Habitat

This species inhabits the uppermost layers of sphagnum moss carpets and lichen-rich surfaces on rocks and tree bark in old-growth boreal forests. It requires consistently high humidity levels and stable temperatures found in undisturbed forest floor microsites and shaded rock crevices.
