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.

here's the underside and the yellow patterned legs. bottom side

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.

That’s maybe an oriental spiny orbweaver (Gasteracantha geminata), according to its appearance and location. You can find many more observations of such spiders on iNaturalist: https://www.inaturalist.org/taxa/207992-Gasteracantha-geminata?locale=en-GB

However, I don’t know what advantage there is to the “spines”. They are not the only species. There’s a whole genus of them with at least 70 known species, according to Wikipedia: https://en.m.wikipedia.org/wiki/Spiny_orb-weaver
