Wasp Spider, Banded Garden Spider
Argiope bruennichi
Family Araneidae (Orb-Weavers), Order Araneae
Physical Description
Robust body with a distinctly oversized, oval-shaped abdomen that overhangs the spinnerets and a smaller cephalothorax covered in fine silver-white hairs. Noticeable sexual dimorphism is present, with females being significantly larger and more brightly colored than males.
Size Estimate
Female body length is approximately 15mm to 22mm with a leg span reaching up to 40mm to 50mm, representing a fully grown adult specimen.
Coloration & Markings
Striking and vibrant alternating bands of bright yellow, black, and white across the dorsal abdomen, resembling the warning coloration of a wasp or hornet. The legs feature distinct dark brown and yellowish banding.
Web Type
Typical vertical orb web constructed close to the ground among tall grasses and vegetation, featuring a prominent zigzag silk structure down the center known as a stabilimentum.
Eye Arrangement
Eight small eyes arranged in two distinct rows on a low tubercle on the cephalothorax, typical of orb-weavers, with lateral eyes often grouped in pairs.
Leg Characteristics
Long, slender legs with dark and light banding, typically held in pairs pointing outward in an 'X' shape when resting at the center of the web.
Venom & Safety Information
Venom Information
Contains neurotoxic venom tailored for immobilizing insect prey. While capable of delivering a defensive bite to humans, it is generally harmless and rarely penetrates thick skin.
Medical Significance
Not medically significant. A bite may cause minor, localized pain, redness, or swelling similar to a mosquito or bee sting, subsiding quickly without treatment.
Safety Recommendations
Admire from a distance and avoid handling bare-handed to prevent accidental bites. If found indoors, gently guide the spider into a container using a piece of paper and release it outside.
Habitat & Behavior
Habitat & Range
Widely distributed across Europe, North Africa, and parts of Asia, preferring open, sunny habitats such as tall grasslands, meadows, heathlands, and rough pastures.
Behavior & Temperament
Docile and non-aggressive toward humans. When disturbed in its web, it will often bounce violently up and down to blur its image or drop to the ground and hide.
Diet & Prey
Generalist predator feeding primarily on grasshoppers, flies, bees, and other medium-sized flying or jumping insects intercepted by the orb web.
Seasonal Activity
Peak adult activity occurs in late summer through early autumn (August to October), which is the primary mating season before adults die off with the first frosts.
Description
The Wasp Spider is one of Europe's most striking and easily recognizable orb-weavers. With its brilliant yellow-and-black abdominal banding mimicking a stinging insect, it hangs conspicuously in the center of its intricate geometric web woven low among sun-drenched meadow grasses, making it a favorite subject for nature enthusiasts.
Key Features
Vibrant yellow, black, and white transverse banding on a large oval abdomen, paired leg resting posture, and the presence of a distinct central web stabilimentum.
Similar Species
Argiope lobata, which features a heavily lobed abdomen, and Argiope aurantia (Black and Yellow Garden Spider), which is found in North America and has different cephalothorax patterns.
Life Cycle
Females construct brown, papery egg sacs hidden low in vegetation in late autumn containing hundreds of eggs. Spiderlings hatch in spring and disperse via ballooning.
Ecological Importance
Serves as an effective natural controller of grasshopper and flying insect populations while providing a food source for birds and small mammals in grassland ecosystems.
Conservation Status
Currently of Least Concern globally with stable populations, though local populations can be affected by the destruction of undisturbed grassland habitats.
Interesting Facts
The distinctive zigzag silk ribbon (stabilimentum) in the web may help camouflage the spider, warn off large grazing animals, or attract prey by reflecting ultraviolet light.
Photography Tips
Use a macro lens on a calm day when wind won't blur the web. Shoot from the side or slightly above to capture the striking abdominal banding and the full symmetry of the orb web.
