The caterpillar of the Common Baron butterfly (Euthalia aconthea) is a significant pest of mango trees (Mangifera indica), known for causing notable defoliation as it feeds on mango leaves, reducing the plant's vigor. It is native to Sri Lanka, India, and Southeast Asia. The caterpillar has a bright green body with a yellowish-white, or sometimes blue, line down its back, covered in branched spines that help it blend into the leaf. Active primarily at night, the caterpillar lies flat along the center vein of a leaf to hide from predators, resembling a harmless plant structure. This caterpillar's ability to blend seamlessly with its environment is a specialized defense mechanism, while its feeding habits make it a notable subject in agricultural studies, especially in areas with significant mango cultivation. Here, a Common Baron butterfly (Euthalia aconthea) caterpillar takes shelter, camouflaged on a mango leaf in Tehatta, West Bengal, India, on October 29, 2025.
