During this season, esp., I have to be watchful for this caterpillar's excreta under the Oleander plant. It is not easy to locate it on the plant. The excreta is an indication of its presence up there, munching off young leaves and blooms. Another index is that of less profusion of blooming - this eats up all the blooms quickly! I guess this is a stage of some butterfly. Which could be that one? I have removed it out of the shrub for taking pictures.
