who, when, where

Pin It now!
... those are the questions ...
(pictures taken from 0640 to 1717 hrs)

April 4th, in the early morning, as I opened the French doors to welcome the new day, 
I noticed this 'bump' ....
Who is this little fellow, wrapped in a camouflage leaf toga ?
Is it a caterpillar or ...?

 Are the eyes peering out through the slit mask ?
And see the 'veins'/striations on the 'toga' - similar to the Curry leaves.
And within 5 hours, the twig had become barren!

 What a rolled leaf backside view! 
Err, don't start getting naughty ideas (it's too small) ;-P

Turns out he 'masked head' is a late April Fools prank .... 
the small brown fuzzy head is under that broad slit mask! 

I saw it turning twice – once at noon and again in the evening, 
but could not capture it in time.
 Here the head is a bit more visible - 
that brown nub peeping out from under 'helmet'.

Notice how barren that same twig has become (leaves from nearby twigs were 
also devoured through the day, though not seen here).
Interestingly during the larval stage, half-eaten leaves give away their presence.
But now, the Entire Leaf disappears!

The last pic was taken in the evening - after 5pm. At 8pm, we went to see how it was - whether it had woven itself into a cocoon or was ready to open it's wings... Huh, it had disappeared completely !!!
Had the green 'leaf' wings opened up and let the moth/butterfly take to the air in such a short span? No bird came to peck it away - I'm sure of it.

When I tried a Google Images search it said this was a lizard. Ughhh! 

So help me answer the question(s). 
What or who is this? At what stage?
Where did it go?
Could it have opened it's wings at night?

I must confess that I should know the answer, having a Masters in Zoology, but well, tatting has devoured what little brain I had ;-P I'm still charmed and amazed - Adaptation, especially morphological, has been a particularly favourite subject in Ecology. 

Spring is the best - new life everywhere ! 

UPDATE : Thanks to the enthusiastic response, the questions are answered. It is a Common Mormon Butterfly caterpillar - 5th instar stage, ready to pupate. Here is an excellent article with pics of each stage . 
There are usually only 2 types of butterflies that visit our balcony - this large black beauty and the smaller yellow ones. I should've started my search from there! But blogging makes you lazy - it's easier to ask and wait for answers ;-P
Now let's wait and see if the butterfly emerges ....
