The Baron Caterpillar (Euthalia aconthea gurda) is native to India and Southeast Asia.

The Baron Caterpillar (Euthalia aconthea gurda) is native to India and Southeast Asia. They are about 4mm long with small spikes when they hatch, but as they reach their 4th and 5th stage of growth (known as instars), they can grow to be about 45mm, with much more elongated spikes. These spikes, along with the caterpillar’s colour, allow it to blend in with leaves to avoid predators until it’s ready to mature.
