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

在陆地上, 粗略估计

它吃什么？

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

怎样认出它

A large, usually triangular white spot in the centre of the abdomen, with two smaller spots below it.1
Iridescent green chelicerae (the front mouthparts).1
White banding with fringes on the legs and pedipalps, which is more prominent in males.1
Males have more striking markings than females and tufts of hair over their eyes.1
Large forward-facing eyes, as with all jumping spiders.1

常被误认为： Phidippus regius has a similar abdominal pattern and lives in the same area of the southeastern United States. In the bold jumper the pale spots near the rear are more linear, while in P. regius they are more oval. The bold jumper also has pairs of matte black patches on its abdomen, which P. regius lacks.1

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

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

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

谣言粉碎机

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

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