Jumping spiders are members of the spider family Salticidae, a large and diverse group known for their powerful jumps and excellent vision. They are active hunters that stalk and pounce on prey rather than catching it in webs, and most species are harmless to humans.
Classification and diversity
Jumping spiders belong to the family Salticidae, which is widely described as the largest and one of the most diverse spider families. Published sources give estimates of about 4,000 to more than 6,000 described species worldwide.
Physical traits and hunting
These spiders are typically small and are known for their vivid colours, strong legs, and forward-facing eyes. They actively hunt by sight, stalking prey and making short leaps instead of using webs as snares.
Habitat and distribution
Jumping spiders occur nearly worldwide and are especially common in tropical regions, though some live in northern and Arctic areas. They are often found in gardens, fields, grasslands, and other outdoor habitats.
Ecology and human interaction
Jumping spiders eat insects and other small arthropods, making them useful natural pest controllers. They can bite if threatened, but their venom is generally not considered dangerous to humans.
Key facts
- Jumping spiders are a family of spiders, not a single species.
- They are named for their ability to jump long distances relative to body size.
- They do not rely on capture webs to catch prey; they stalk and pounce instead.
- Their large forward-facing eyes give them unusually good vision for spiders.
- Most jumping spiders are considered harmless to humans and rarely bite.
Jumping spiders are found in Canada, including many species in outdoor habitats across the country, and they are commonly encountered in gardens and other human-influenced environments.[1][2][13]
