Germany is home to a diverse range of spider species, many of which are harmless but often misunderstood. This list covers the most common and notable spiders found across the country, providing detailed insights for enthusiasts, homeowners, and anyone curious about the arachnid residents of Germany. Whether you’re concerned about bites or simply interested in local wildlife, understanding these spiders can help demystify their presence in your environment.
Common House Spider (Tegenaria domestica)
The Common House Spider, known scientifically as Tegenaria domestica, is one of the most widespread spiders in German homes. They are typically brown or gray with a body length of about 10-15 millimeters, and they often build funnel-shaped webs in corners, basements, or garages. Despite their intimidating appearance, they are harmless to humans and play a beneficial role in controlling other pest insects indoors.
Cellar Spider (Pholcus phalangioides)
Often called daddy long-legs, Cellar Spiders are easily recognizable by their long, spindly legs and small bodies, usually around 8-10 millimeters. They are common in cellars, basements, and dark corners of homes, where they spin messy, irregular webs. While their appearance can be unsettling, they are non-aggressive and help reduce populations of flies and other insects.
European Garden Spider (Araneus diadematus)
The European Garden Spider, or Araneus diadematus, is notable for its distinctive cross-shaped markings on the abdomen. They are large, with a body size of up to 20 millimeters, and construct orb-shaped webs primarily in gardens, forests, and parks. These spiders are beneficial predators of flies and moths, making them a welcome presence in natural and cultivated areas.
Walckenaer’s Garden Spider (Araneus walckenaeri)
This species is similar to the European Garden Spider but tends to prefer more wooded or shrub-rich environments. Walckenaer’s Garden Spiders are slightly smaller and have a more muted coloration, with brown and gray patterns. They are active during late summer and fall, helping control insect populations in their habitats.
Nursery Web Spider (Pisaurina mira)
The Nursery Web Spider is often mistaken for a wolf spider due to its robust body and active hunting style. They are about 15-20 millimeters long and are frequently seen stalking prey or resting on foliage. These spiders are non-venomous to humans but are valued for their role in controlling pest insects in gardens and fields.
European Black Widow (Latrodectus tredecimguttatus)
While rare, the European Black Widow has been occasionally spotted in Germany, mainly in southern regions. Recognizable by its shiny black body and distinctive red markings, this spider is venomous, but bites are uncommon and rarely dangerous to humans. They prefer secluded, undisturbed locations such as sheds or woodpiles.
Zebra Jumping Spider (Salticus scenicus)
The Zebra Jumping Spider is a small, agile species characterized by its black and white striped pattern. Measuring about 5-7 millimeters, it is often seen jumping across walls and windowsills. Their excellent vision and quick movements make them fascinating to observe, and they pose no threat to humans.
Tube Web Spider (Segestria florentina)
This large, striking spider is known for its metallic blue-green coloration and distinctive habit of hiding in silk-lined tubes or crevices. They are about 15-20 millimeters long and are found in dark corners, under rocks, or in building cracks. Despite their intimidating appearance, they are harmless but should be avoided due to their potent venom.
European Wolf Spider (Lycosidae family)
Wolf spiders are robust, fast-moving hunters that do not spin webs but actively chase their prey. In Germany, species like Lycosa tarantula are common, with a body length of up to 20 millimeters. Their brown or gray coloration provides excellent camouflage in natural habitats, and bites, while painful, are rarely serious.
How to Choose
When selecting or identifying a spider, consider factors like size, web type, habitat, and behavior. Most importantly, understand whether the spider is harmless or potentially dangerous. For those interested in natural pest control, species like orb-weavers and jumping spiders are beneficial. If safety is a concern, learn to distinguish venomous species such as the European Black Widow or Tube Web Spider. Remember, most spiders in Germany are harmless and play a vital role in the ecosystem.
