Overview

Thanatus striatus is a species of running crab spider in the family Philodromidae. It is found in North America, Europe, Turkey, a range from Russia, and Central Asia.

The duinrenspin faces significant threats from habitat loss due to coastal development and dune stabilization projects that alter its specialized sandy habitat. Climate change and increased storm intensity threaten the fragile dune ecosystems this species depends on, while recreational activities and tourism development further fragment and degrade suitable habitat.

Threat summary

Habitat

Inhabits coastal sand dunes, sandy heathlands, and dry grasslands near shorelines, particularly favoring sparsely vegetated areas with loose sand and low shrub cover. The species is specifically adapted to dynamic dune systems and sandy soils in coastal environments.
