对人的危险: 很疼可能真的很疼，但几乎从不严重。

The white widow is a spider that is light-coloured, from beige to white, unlike most of its dark relatives. It lives in dry steppes and deserts across North Africa, the Middle East and central Asia. Its bite is venomous and can be medically significant, so it is worth knowing what it looks like.1

怎样认出它

  • Light-coloured, with a colouring ranging from beige to white1
  • Darker legs than the body1
  • No bright red markings, unlike other widow spiders such as the black widow or redback spider1
  • Otherwise similar in shape to other spiders of the genus Latrodectus1

常被误认为： Most widow spiders are dark, and the white widow is distinguished mainly by its pale colouring and lack of red markings. Other than colour, it resembles other Latrodectus spiders.1

毒液之力

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？

Its venom is neurotoxic in type, meaning it acts on the nerves, as is typical of Latrodectus species. Toxicology studies report that its venom is similar in structure to that of the Mediterranean black widow, L. tredecimguttatus. It is considered less toxic than the bites of L. mactans or L. hasselti.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

The bite is medically significant and can injure humans. It can kill children and people who are infirm, although it is not nearly as toxic as the bites of some other widow spiders. A poster by the Egyptian Society of Natural Toxins describes its venom as moderately venomous.1

如果它咬人

  • 清洗咬伤处，用冰袋冷敷止痛。如果疼得厉害、疼痛扩散或感到不适，就去看医生。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。 急救基础

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

事实

1

Males are sometimes cannibalised by the female after mating.1

2

After maturity, male widow spiders do not feed and spend most of their lives searching for females, which is why they are smaller than females.1

3

Widow spider males generally live with a female for a long period and provide energy-demanding courtship displays.1

4

The white widow is comparatively rare compared to other widow spiders in its region.1
