Zebra Spider, Zebra Jumper
Salticus scenicus
Salticidae (Jumping Spiders), Order Araneae
Physical Description
A compact, stout spider with a relatively flat cephalothorax and an oval-shaped abdomen. The body is covered in dense hairs, giving it a velvety appearance. It possesses the characteristic large, forward-facing eyes typical of jumping spiders.
Size Estimate
Body length 5-9mm; leg span approximately 10-15mm. This appears to be an adult specimen.
Coloration & Markings
Distinctive black and white striped pattern resembling a zebra. The abdomen features prominent white transverse bands on a dark brown or black background. The legs are often banded or mottled with similar colors.
Web Type
None. This is a hunting spider that does not build webs for prey capture, though it creates small silk 'retreats' for resting and molting.
Eye Arrangement
Eight eyes in three rows. The front row has four eyes, with the two Anterior Median Eyes (AME) being very large and prominent, providing high-resolution binocular vision.
Leg Characteristics
Short, powerful legs designed for jumping. They are densely haired and somewhat stout compared to web-building spiders, providing the traction and power needed for pouncing.
Venom & Safety Information
Venom Information
Neurotoxic venom tailored for small insects; however, it is not potent enough to pose a threat to humans or pets.
Medical Significance
Harmless to humans. Bites are extremely rare and typically result in no more than mild, localized redness or itching, similar to a mosquito bite.
Safety Recommendations
No action is required as they are beneficial. If found inside, they can be safely relocated outdoors using a cup and a piece of paper.
Habitat & Behavior
Habitat & Range
Holarctic distribution (North America, Europe, Northern Asia). Commonly found on sunny vertical surfaces such as rocks, fences, and the walls of buildings/homes.
Behavior & Temperament
An active, diurnal hunter with high intelligence. It stalks prey like a cat before pouncing from a distance. They are curious and generally flee from humans rather than showing aggression.
Diet & Prey
Small insects including flies, mosquitoes, moths, and other spiders. They use their exceptional vision to track movement and jump several times their body length to tackle prey.
Seasonal Activity
Most active during spring and summer months when they can be seen basking in the sun; they overwinter as sub-adults in silk-lined crevices.
Description
The Zebra Spider is one of the most charismatic and easily recognized jumping spiders. Identified by its striking black and white stripes, it acts as a tiny, highly efficient predator that patrols the exterior walls of suburban homes. Its jerky, alert movements and large front eyes give it a 'curious' appearance as it navigates its environment.
Key Features
Black and white zebra-like stripes on the abdomen; four large eyes on the front of the face; jerky, stop-and-go movement; tendency to be found on man-made structures.
Similar Species
Salticus cingulatus (lives mostly on tree bark); various other Salticus species which lack the specific vivid white banding of S. scenicus.
Life Cycle
Females lay eggs in a silk sac within a retreat. Spiderlings emerge and are self-sufficient early on. They have a lifespan of about 1-2 years and go through several molts to reach maturity.
Ecological Importance
Excellent natural pest control, consuming significant numbers of common household insects like flies and mosquitoes.
Conservation Status
Not evaluated by the IUCN, but remains common and widespread throughout its range with stable populations.
Interesting Facts
Before jumping, they attach a silk 'dragline' to the surface as a safety rope. They have also been observed reacting to their own reflections and can track laser pointers.
Photography Tips
Focus on the 'face' to capture the large primary eyes. Use a fast shutter speed or flash to freeze their rapid, jerky movements. Macro lenses are essential due to their small size.
