怎麼認出牠

The cephalothorax (front body section) has two dark stripes.1
The abdomen (back body section) has one stripe of the same colour as the stripes on the front.1
Other parts of the body are yellow.1
It has eight eyes: four above and four below. The lower pair looks more like a moustache.1
Females are larger than males, with a body length of about an inch. Males are about half an inch.1

常被誤認為： It is often compared with Rabidosa punctulata. In males of R. rabida, the front legs are mostly black. In R. punctulata, all the legs are the same colour.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

值得知道

小知識

When prey enters its silk sheet, it can detach the anchor points and move the silk to wrap the prey up.1

Spiders cannot have rabies, so they cannot pass it on to people or other animals.1

It can camouflage itself to look like bark or leaves when hunting.1

During courtship, the male performs a "dance" in front of the female and makes sounds by stridulation (rubbing body parts together).1

Spiderlings ride on their mother's back until they are old enough to live on their own.1

Its lower pair of eyes looks like a moustache.1

破解迷思

迷思： A rabid wolf spider has rabies and can give it to you.

真相： Spiders cannot have rabies. The name comes from the spider's erratic, rapid movements.1
