Leptothrix hardyi

Unknown

Overview

Leptothrix is a monotypic genus of dwarf spiders containing the single species, Leptothrix hardyi. It was first described by Anton Menge in 1869.

Primary threats to L. hardyi include habitat fragmentation due to logging and urban development, which disrupts the continuity of old-growth forest patches essential for population connectivity. Climate change poses additional pressure through altered precipitation patterns that affect the moisture-dependent microhabitats where this species establishes its webs.

Threat summary

Habitat

This species inhabits the understory of mature coniferous and mixed forests, particularly favoring areas with high humidity and dense canopy cover where it constructs small, irregular webs between moss-covered tree trunks and fallen logs. It shows strong preference for microhabitats with stable moisture levels, often found in forest ravines and north-facing slopes with minimal direct sunlight exposure.

Frequently asked questions

Why is Leptothrix hardyi classified as Endangered?
Leptothrix hardyi is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Primary threats to L. hardyi include habitat fragmentation due to logging and urban development, which disrupts the continuity of old-growth forest patches essential for population connectivity. Climate change poses additional pressure through altered precipitation patterns that affect the moisture-dependent microhabitats where this species establishes its webs.
Where does Leptothrix hardyi live?
Leptothrix hardyi occurs in Belgium, Denmark, Finland, France, Germany, and Isle of Man (plus 7 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 Leptothrix hardyi?
The main threats to Leptothrix hardyi are habitat loss and human disturbance. The full IUCN-classified threat record for this species is detailed on the species page.
