Eidmannella pallida
Pallid cave spider
Eidmannella pallida is a scaffold-web spider in the family Nesticidae with native distribution in North America and established invasive populations across multiple global regions. The species has been introduced to Pacific Islands, the Galápagos Islands, Macaronesia, Spain, Japan, and Italy, where it demonstrates high invasiveness potential. It readily establishes permanent populations in anthropogenic habitats including vineyards, annual crop fields, and olive groves, and shows particular tendency to exploit vulnerable subterranean ecosystems such as caves.
