Caterpillar (playing dead)

Description:

This caterpillar plays dead so convincingly. It was on a potted plant. (photo 1). Only the frass and nibbled leaves gave it away so well did it blend with the stem. When I tried to photograph it, it fell to the ground and played dead (photo 2) and when I placed the leaves near it ....it went home happily (photos 3, 4 and 5)

Habitat:

My rooftop terrace. On a potted Euphorbia milii or Crown of thorns/ Christ plant.

Notes:

Had heard about the Hognose snake and paying possum idiom....this one is in the same league.
