The cupboard spider is a common house spider that lives in dark corners and builds messy, three-dimensional webs. It is often mistaken for the dangerous black widow, but its bite is usually minor. Its name shows that it is found in many parts of the world, including Europe, temperate Asia and areas where it has been introduced.1

怎样认出它

Adult females are 6 to 10.5 mm long, dark coloured and round-bodied, with a bulbous abdomen.1
Typical colour ranges from purplish brown to black, with light-coloured markings.1
It has no bright red hourglass pattern or other bright, distinctive markings.1
Males are thinner and can be nearly as long as females, at 4.1 to 10 mm.1
Sexually mature males have lighter, more reddish legs than females.1

常被误认为： It is often confused with black widows and redbacks (Latrodectus species), which have a bright red hourglass pattern that this spider lacks. Steatoda borealis is similar in shape but slightly smaller and found in colder climates. It has coloured markings on the top of the abdomen rather than the underside.1

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

The bite is minor in humans and has no long-lasting effects. Symptoms can include blistering at the bite site and pain. A few cases have included fever, nausea, sweating and a general feeling of being unwell that lasted several days.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

The spider is not aggressive. Most injuries to people happen when a spider is accidentally squeezed or pinched and bites in defence. It is possible that a spider may bite a finger pushed into its web by mistake.1

好消息：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

It usually flees when a large creature comes near, and it bites when it is squeezed or pinched.1

如果它咬人

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。

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

事实

Director Sam Raimi chose this spider to play the radioactive spider that bites Peter Parker in the 2002 film Spider-Man. The filming spider was painted with red and blue makeup.1

The spider reportedly preys on black widows, which can make it useful to have around.1

It can go several months without feeding, as long as it has access to water.1

Females can live up to six years, while males typically live 1 to 1.5 years and often die shortly after mating.1

谣言粉碎机

谣言： It is a dangerous widow spider, just like the black widow.

真相： Its bite is minor in humans and has no long-lasting effects, although it can cause pain, blistering and, in a few cases, several days of feeling unwell.1
