In brief
Jumping spiders (family Salticidae) are small, sharp-eyed hunters found on sunny walls, plants, and woodlands worldwide. Most are just 1 to 2 cm (0.4 to 0.8 in) including their legs, yet they have superb vision and can leap many times their body length to pounce on prey.

Jumping spiders (family Salticidae) are small, sharp-eyed hunters found on sunny walls, plants, and woodlands worldwide. Most are just 1 to 2 cm (0.4 to 0.8 in) including their legs, yet they have superb vision and can leap many times their body length to pounce on prey. Rather than build webs to catch food, they stalk and ambush insects by day. Individuals typically live about a year and are of Least Concern.

Key Facts: Jumping Spider
- Jumping spiders are compact and often furry, with most species measuring just 1 to 2 cm (0.4 to 0.8 in) including the legs.
- Rather than snaring prey in a web, jumping spiders are active daytime hunters that stalk and pounce.
- Jumping spiders do not have large muscles in their legs to power a jump.
Appearance and remarkable eyes
Jumping spiders are compact and often furry, with most species measuring just 1 to 2 cm (0.4 to 0.8 in) including the legs. Their standout feature is a set of eight eyes, dominated by two large forward-facing eyes that give them the sharpest vision of any spider. This excellent eyesight lets them judge distance accurately before a leap and recognise prey, mates, and rivals. Many species are boldly patterned, and the males of some are strikingly colourful.
How jumping spiders hunt
Rather than snaring prey in a web, jumping spiders are active daytime hunters that stalk and pounce. Using their keen eyes, a spider will spot an insect, creep closer, carefully line up the distance, and then leap onto it with a precise pounce. Before jumping it anchors a silk dragline to the surface, which acts as a safety line if it misses. They do not run down their prey over long distances, relying instead on stealth and a sudden, accurate leap.
The secret of the leap
Jumping spiders do not have large muscles in their legs to power a jump. Instead they rapidly increase the blood-like fluid pressure inside the body, which extends the rear legs almost explosively and launches the spider forward. This hydraulic mechanism lets them leap many times their own body length despite an overall crawling speed of only about 1.6 km/h. The trailing silk dragline helps steady them in flight and lets them climb back if a jump falls short.
Diet and behaviour
Jumping spiders are carnivores that feed on insects and other small arthropods, including flies, moths, and even other spiders. A few species supplement their diet with nectar or plant matter, and some specialise in hunting particular prey. They are curious and alert by nature, often turning to face and track movement, which gives them an unusually inquisitive appearance. Being active by day, they are among the spiders people most often notice on sunlit walls and leaves.
Courtship and life cycle
Male jumping spiders perform elaborate courtship displays, waving their legs and, in some colourful species, showing off bright body patterns to females. After mating, the female lays eggs in a silk nest, often tucked under bark or a leaf, and may guard them until the young hatch. Most jumping spiders live for around a year, growing through a series of moults before reaching adulthood. They are harmless to humans and are of Least Concern.
What WARN Does
WARN does not run a dedicated jumping spider programme — this guide is part of the World Animal Rescue Network's free educational library. The jumping spider is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the jumping spider supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.
If clear, science-based wildlife guides like this help you understand and value animals, please consider supporting the World Animal Rescue Network's educational and rescue work so we can keep producing them.
