Zebra Spider, Zebra Jumping Spider
Salticus scenicus
Salticidae (Jumping Spiders), Order Araneae
Physical Description
Compact and robust body with a distinctively high, blunt face and large anterior median eyes. The cephalothorax is broad and somewhat rectangular, while the abdomen is oval and slightly flattened. The body is covered in fine, dense setae (hairs) giving it a velvety appearance.
Size Estimate
Body length typically ranges from 5 to 9 millimeters, with males usually slightly smaller than females. Leg span is proportionate, approximately 10 to 15 millimetres.
Coloration & Markings
Striking contrasting pattern of black and white bands or patches, resembling a zebra. The abdomen features alternating dark and light transverse stripes, while the cephalothorax displays white lateral bands and facial markings.
Web Type
Does not build a traditional web to catch prey. Instead, it spins small silken retreats or relay stations where it rests at night or during molting, using safety draglines wherever it jumps.
Eye Arrangement
Eight eyes arranged in three rows characteristic of jumping spiders: a prominent front row of four very large eyes (with the anterior median eyes exceptionally large and capable of high-acuity, color vision), a tiny middle row, and two medium-sized eyes set further back on the cephalothorax.
Leg Characteristics
Relatively short, stout legs designed for powerful leaping rather than running. The front legs are often slightly more robust in males. Legs feature distinct dark and light banding patterns.
Venom & Safety Information
Venom Information
Possesses mild neurotoxic venom used primarily to subdue small insect prey. The venom is specialized for arthropods and holds no medical significance for humans.
Medical Significance
Harmless to humans. Mouthparts are generally too small to effectively puncture human skin, and bites are exceedingly rare. Even in the unlikely event of a bite, symptoms are typically minor or non-existent, requiring no medical treatment.
Safety Recommendations
No special precautions needed as they are completely harmless. If relocation is desired, gently guide the spider into a small container using a piece of paper.
Habitat & Behavior
Habitat & Range
Widespread across the Holarctic ecozone, including North America, Europe, and northern Asia. Commonly found in sun-drenched vertical surfaces such as stone walls, rocks, fences, tree trunks, and the exterior walls of buildings.
Behavior & Temperament
Active diurnal hunter relying on exceptional eyesight to stalk and pounce on prey. Highly curious, alert, and capable of jumping distances many times its own body length. Generally docile and harmless toward humans, though quick to flee or leap away when disturbed.
Diet & Prey
Carnivorous predator feeding on a wide variety of small insects including flies, mosquitoes, aphids, and other small arthropods. Stalks prey like a cat before executing a rapid, calculated spring.
Seasonal Activity
Most active during spring and summer months when weather is warm and sunny. Overwinters as immature or adult spiders hiding in protected silk retreats under bark or in crevices.
Description
The Zebra Spider is one of the most recognizable and charismatic jumping spiders, easily identified by its bold black and white stripes. Navigating sunny walls and fences with characteristic jerky movements and impressive leaps, this diminutive hunter is a welcome guest in gardens and around homes due to its voracious appetite for pest insects.
Key Features
Distinctive black and white zebra-like striping, exceptionally large front-facing eyes, and characteristic bounding, alert posture on vertical surfaces.
Similar Species
Other jumping spiders in the genera Salticus or Phidippus, which can be distinguished by different coloration patterns, lack of strict black-and-white striping, or larger overall body sizes.
Life Cycle
Mates in spring, after which females construct a silken egg sac in a protected crevice or under bark, guarding the eggs until they hatch. Spiderlings undergo several molts to reach maturity, typically living for one to two years.
Ecological Importance
Acts as an effective natural pest controller by preying on common household and garden insect pests. Serves as a vital food source for small birds, lizards, and larger insectivores.
Conservation Status
Not evaluated by the IUCN, but populations are secure, widespread, and highly adaptable to human-altered environments.
Interesting Facts
Zebra spiders possess some of the sharpest vision in the invertebrate world, capable of seeing in color and tracking movement up to 30 centimeters away. They can jump up to 50 times their own body length using a sudden hydraulic pressure change in their legs.
Photography Tips
Use a macro lens with a ring flash or diffuser to capture fine details of the eye arrangement and hairy texture. Approach slowly during daylight hours when they are basking in the sun on vertical surfaces.
