White widow

Latrodectus pallidus
名字的由來: It is named for its pale, white-to-beige colouring, which sets it apart from the dark widow spiders.1
只是會痛會痛,但不會對你造成嚴重傷害。

對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。

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

怎麼認出牠

  • 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

常被誤認為: 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

毒液力量

咬

咬的時候,毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用?

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

牠對人有多危險?

對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。

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

如果牠咬人

  • 清洗咬傷處,用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服,要就醫。

一定要先打緊急電話(112、000、911)。這是一般急救指引,不是醫療建議。 急救基本知識

注意安全

  • 絕對不要碰、抓或捉弄野生動物,就算是很小的動物,就算牠看起來在睡覺或已經死了也一樣。
  • 給牠空間。如果遇到了,保持冷靜,慢慢往後退,讓牠自己離開。
  • 如果被牠咬了:保持冷靜,保持不動,打緊急電話(112、000、911)或趕快去醫院。記住牠的樣子,有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己,而且牠更想躲起來。 更多安全知識

小知識

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
