Description and Identification

Caterpillar

The newly emerged larvae appear yellow with black head and two horns rising from its thorax’s second segment. During the initial stage, they remain together and primarily consume the leaf’s soft parts skeletonizing it completely. They gradually shed their skin and head capsule entering the second stage, where they have a yellow coloration. In their third and fourth phase, they turn black with stripes of yellow running through their body. They even develop spiny projections on their back.
