Lappet Moth Caterpillar

Thank you very much, bayucca. Its body is violet-blue rather than yellow as in Trabala vishnou. So it is better call it Trabala sp.

Lasiocampidae, Trabala sp., could be Trabala vishnou, but I am not 100% sure and many IDs on the net are not really trustable.
But look at this link with the same caterpillar and the freshly emerged moth, it might really be Trabala vishnou:

Please, verify! If we are not sure about Vishnou, I would go with Trabala sp.
