Cereal Leaf Beetle
A small beetle with metallic blue-black elytra and a red-orange thorax. Its larvae strip the upper leaf surface of cereal crops.
Did You Know?
Larvae carry a shield of their own faeces on their backs to deter predators and prevent desiccation.
Corn Earworm
A highly polyphagous moth whose caterpillars feed inside corn ears, tomato fruits, and cotton bolls. It is one of the costliest crop pests in the Americas.
Did You Know?
Caterpillars are cannibalistic, so usually only one survives per corn ear.
