Overview
- Citizen-science portals and NABU have recorded an unusually high number of reports in 2026, with more than 2,500 photos submitted between January and May, signaling a marked rise in detections.
- Records show the Mediterranean species Zoropsis spinimana, first found in Germany in 2005, is now reported farther north including the Baltic islands Rügen and Usedom and in northern states such as Schleswig-Holstein.
- State data show a west–east gradient in occupancy with higher densities in western states and Berlin and growing but lower-frequency records in eastern areas like Saxony around Dresden and Leipzig.
- The spider is nocturnal, often shelters on warm walls or inside buildings, can bite and is venomous, but experts say bites usually cause only local pain or swelling and pose little danger to people.
- Because the species is not classified as invasive under federal law, formal state monitoring is not mandated, leaving tracking to NABU volunteers and citizen reports and making public reporting important for mapping its spread.
