Zimbabwe brown button spider

Latrodectus rhodesiensis

只是會痛會痛，但不會對你造成嚴重傷害。

咬吃：肉

The Zimbabwe brown button spider is a small, venomous spider that lives in parts of southern Africa. It is one of the brown button or brown widow spiders, a group of relatives of the black widow. Its bite can cause unpleasant symptoms, but it is not usually as venomous as the black button or black widow spiders.1

怎麼認出牠

Builds a web low down in vegetation1
Its egg sac is smooth and spherical1
The egg sac is pure white when first made and becomes dirty white with age1
The egg sac has a thin inner sac surrounded by a layer of fluffy threads1

常被誤認為： Its web is placed low in vegetation, much like that of Latrodectus geometricus. Its egg sac is different from those of other African species of the same genus, so the egg sac is one way to tell them apart.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？

Like all Latrodectus species, it has a neurotoxic venom, which is a venom that acts on the nerves. It acts on nerve endings and causes latrodectism, a set of very unpleasant symptoms in people who are bitten.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。

Brown button spiders are not generally as venomous as black button or black widow spiders, such as L. indistinctus.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
