Hairy caterpillars are a major pest of cardamom crops. These caterpillars are voracious feeders and can quickly defoliate entire cardamom plants. They are gregarious in nature, meaning they live in groups. During the day, they congregate on the trunks of shade trees that are often grown alongside cardamom plants. At night, they descend on the cardamom plants to feed.
