Today I saw this curious colorful spider on its web near a sapota tree in my garden. I have never seen any spider like this,its around 2cm or a little less.
The most curious part is this part of its exoskeleton which looks like when a moth rests.Like a cape.
But the spider was bothered by my presence and was trying to crawl away,and I took this angled shot:
I live in South India.
So what is this spider ?
Is there any advantage of the wing like part?
Links to websites with details of the spider are also appreciated.
