Spiny Oak-Slug Moth

Agree with Bayucca... I must made mistake in suggestion...

Euclea delphinii is a US species and not found in India!

Yes, definitely a Limacodidae.

Reminds me of the saddleback caterpillar - but that's an American species. Perhaps the same family: Limacodidae

I don't think that this one is an Euclea sp. These are only found in the Americas.

Wow! Absolutely beautiful!!

Fractal Insect! Wow!

Awesome!

Actually Keith was reached already..!!

Dang! At first I thought this is an abstract painting :D Way cool!

Reminds me of a slug caterpillar, family Limacodidae. Many can inflict painful stings with their spines.

Looks like the Indian equivalent to our saddleback caterpillar http://www.bing.com/images/search?q=saddleback+caterpillar&qs=IM&sk=&pq=saddleback+&sp=1&sc=8-11&form=QBIR

Wow, looks like it has a copper shield!

Not a critter I would like to argue with but fantastic colouring on him!
