怎样认出它

  • Black in colour, with thirteen spots on the upper side of the abdomen.1
  • The spots are usually red, but may also be yellow or orange.1
  • The female has a body length of about 7 to 15 mm. The male is smaller, at 4 to 7 mm at most.1
  • It lays out a web and waits for prey.1

常被误认为： It is similar to other widow species in the genus Latrodectus. The thirteen spots on the abdomen help tell it apart.1

毒液之力

它的毒液会造成什么？

它对人有多危险？

对人的危险: 严重被咬了要去看医生。死亡非常罕见。

Its bite is painful and can be fatal in rare cases. Epidemics of bites have been reported, and Ukrainian farm workers have been bitten in the fields. In Kazakhstan, where it is called karakurt, it has been reported to bite and kill camels. Only the female's bite is dangerous to people and cattle, because the male cannot get through the thick outer skin.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
