The bold jumping spider is a small spider that hunts by sight, leaping onto its prey instead of catching it in a web. It is common across North America and is often found near people, in gardens, fields and on fence posts. It matters because it eats many crop pests.1

En terra, estimación aproximada

Que come?

Bold jumpers are solitary hunters that stalk live prey using their eyesight. They approach until they are within jumping distance, then pounce and grab the prey with their front legs. They prey on caterpillars, dragonflies, grasshoppers and other spiders. They do not build webs to catch food.1

Que fai cando ten medo?

When threatened, they flee by jumping down and away or by hiding in small crevices.1

Se morde

Lava a mordedura e ponlle unha bolsa de xeo para a dor. Busca axuda médica se a dor é forte, se se estende ou se a persoa se sente mal.

Datos

Bold jumpers have some of the best eyesight of any spider. Their vision is widely regarded as the best among all spiders.1

Their four pairs of eyes give them nearly 360° of visual coverage around the head.1

Bold jumpers sometimes invade the webs of other spiders to steal insects that have been caught, or to attack the spiders themselves.1

Bold jumpers can change their behaviour after watching other spiders, which is rare among spiders.1

Females choose mates by watching the male's leg and body movements during his courtship dance.1

Spiderlings often spread to new places by ballooning, a way of travelling on silk threads in the wind.1

Desmontamitos

Mito: Like most spiders, jumping spiders catch their prey in webs.

Verdade: Bold jumpers do not build webs to catch prey. They hunt actively by sight and leap onto their victims.1
