Peacock spider

Maratus volans

名字的由來： The genus name Maratus refers to peacocks, because the males' display is compared to a peacock's fan. The specific name volans is Latin for "flying".1

無害對人無害。不用擔心。

咬吃：肉

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

The peacock spider is a tiny jumping spider from Australia. Males are brightly coloured, and they show off with a fan of flaps on their abdomen and a dance to win a female. Its eyesight is so good that it can see ultraviolet light, which helps it hunt.1

牠吃什麼？

It hunts insects and other spiders during the day. It does not use webs. It stalks its prey with its keen eyesight, then chases and leaps onto it to deliver a fatal bite.1

怎麼認出牠

Males are red, blue and black, with flap-like extensions on the abdomen that have white hairs and can be folded down.1
Females and young spiders are brown, with colour patterns that set them apart from related species.1
Both sexes reach about 5 mm in body length.1
The males raise their abdomen and spread the flaps into a white-fringed, circular field of colour during courtship.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

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

Some males can change their scale colours from red to green to violet with slight movements, because their scales reflect light in a special way.1

Peacock spiders can jump up to 40 times their own body length.1

They have eight eyes and can see ultraviolet light as well as the full visible spectrum.1

Males dance and vibrate their abdomen for an average of about 24 minutes to win a female, and the dance can last from 6 to 50 minutes.1

Females of this species are thought to mate only once.1

破解迷思

迷思： The male spider uses its colourful flaps as wings to help it glide or sustain its leaps.

真相： This belief has been debunked by the Australasian Arachnological Society.1
