這種喜歡賣弄風騷的孔雀蜘蛛 Peacock Spider 只生活於澳大利亞中部地區,曾被美國《連線》雜誌官方網站報導,該網站下屬的《連線科學》欄目去年刊選為十大奇特蜘蛛之一,並且獲得了“最虛榮的蜘蛛”獎項(日後再作介紹)。

孔雀蜘蛛也是跳蛛的一種,它們的體型非常小,身體直徑不超過0.2英寸(約4~6mm),比一般常見的跳蛛(蠅虎)還小。

孔雀蜘蛛雖然只有四毫米長,卻愛炫耀彩虹般的軀體以吸引雌蜘蛛青睞,牠可以抬高一雙腿,像孔雀開屏一樣的展現橘、黃、綠、藍等色澤斑斕的腹部,因而贏得孔雀蜘蛛之名。

雄性孔雀蜘蛛往往會利用其艷麗的色彩和條紋來吸引異性,尋找女朋友。為了能夠找到交尾對象,雄性孔雀蜘蛛會故意在雌性蜘蛛面前搔首弄姿,展示其美麗的腹部,就好像孔雀開屏一樣,並且會不斷的左右搖擺以吸引雌蛛的青睞。




Australia is home to many strange and unusual animals, something the majority of us know. When asked, most people would say that it is the marsupials of the country that are the most significantly different to the rest of the world.  Perhaps that assumption should be questioned - Australia is also home to the tiny Peacock Spider, whose behaviour and appearance is nothing short of startling.





This species waves it legs when first in courtship mode - and you might think that bizarre enough.  Although one should hesitate to anthropomorphize any animals, it does look like he is beckoning prospective partners to him with something akin to a cheeky wave. And perhaps he is, but when he raises a pair of patterned flaps this elaborate courtship process goes from the comically strange to the extraordinary.  There is little wonder why its common name is the Peacock Spider.



The head-breast part (or cephalothorax) of the Peacock Spider are usually a deep brown color with red stripes and the upper abdomen green and patterned with broad stripes of blue and brown.  And then there is the gorgeous pair of flaps which, when he is not in pursuit of a lady friend, lie against his abdomen like the cape of some kind of arachnid super hero.



They they are, down at his sides. Then, it's up for action!





Technically he is known as Maratus volans and he is a jumping spider, found only in the Queensland and New South Wales area of eastern Australia.  The species was first described by Octavius Pickard-Cambridge in the late nineteenth century and he noted, with some understatement that "it is difficult to describe adequately the great beauty of the coloring of this spider".





By now you will have checked the date of this post, so that you know that even though it was posted in April, it wasn't on the first of the month.  This tiny spider is for real. It was originally thought that the amazing flaps were used to aid the spider in gliding, hence the volans in its name.  However, they are used solely for a much more down to earth function than that - they are used to attract the (above, approached by the male and rather drab by comparison) female of the species.





When he wants to catch the fancy of a female the male spider will dance, wave and finally raise his gorgeous abdominal flaps, much in the same way that a peacock raises his dazzling feathers in an altogether quite overt come hither action.





Although a fraction of the size of the avian variety, the Spider Peacock elevates his flaps and reveals a gorgeous display of orange, yellow, green and blue. From our perspective the site is extraordinary - who can say what goes through the mind of the female spider when she catches sight of this amazing spectacle?





Once aroused by the proximity of a female, the spider will vibrate his flaps with his raised legs, no doubt giving their iridescence a little extra shimmer.  Simultaneously he will swagger and roll as he approaches the female. You can almost imagine him singing sea shanties as he does this. The act itself follows.





Once he has mated, this amazing dance will be repeated as often and with as many females as possible.  After all, the more he can impress the more likely it will be that his genes will be passed on to the next generation. And if you've got it, flaunt it.



Super heroes are often associated with large size and it must be said that the Peacock Spider is tiny - adults will at their very largest be a mere 5mm in length.  Yet when it comes to the mating dance this tiny spider shows that when it comes to impressing a female, size is most certainly not everything.

哇,太棒了!
尤其是影片裡的小傢伙們,竟然還會左右獲兩邊同時抬腳,真可愛。
看完影片,才知它所以「開屏」是求偶的舞姿,
那不就和新幾內亞的「太陽鳥」一樣?
真是大開眼界,謝謝樓主!

真漂亮,不過一般彩色蜘蛛都有毒,他怎麼敢直接放在手上。

超漂亮的蜘蛛,像孔雀一樣可以將尾巴打開似的。體積還不到姆指指甲的大小,真的可愛,但不知有毒否?

孔雀开屏不稀奇,蜘蛛开屏才特别!根据ETtoday编译自Daily Mail的一篇报导,昆士兰州和新州等地,有种称为孔雀蜘蛛(Peacock Spider)的奇特物种,雄性蜘蛛腹部色彩斑斓鲜艷,有些还会出现彷彿人类五官的图案。在求偶季节,雄蛛就靠着高举腹部开屏来吸引雌性注意。许多蜘蛛都是雌性体型较大,会在交配后把雄性当作猎物吃掉,“孔雀蜘蛛”也不例外。从文章所附影片中可看到(Peacock spiders from south-east Australia perform mating dances, 约5分处开始),有可能是遇上刚交配过的雌性,雄蛛虽求偶不成,正要赶紧逃离,雌蛛趁机一跳接近将其捕获,成为雌蛛的的嘴下亡魂。孔雀蜘蛛通常在9月到11月进行求偶,澳洲当地正处于春夏季节交替时,雄蛛只要发现同种类雌蛛,就会高举起鲜艷的腹部,与从前往后算起的第三对脚,左右不停晃动,彷彿孔雀开屏一般;有时脚与腹部晃动非常有节奏感,就像在跳定格的机械舞。

This is the first time I have heard of such species of spiders. Usually, I dislike spiders because they look rather creepy, but I have found that little peacock colorful spiders are cute, especially they have to perform dances for their love ones.
The video was remarkably well done.
