What are Locusts?

Locusts are large herbivorous insects that can be serious pests of agriculture due to their ability to form dense and highly mobile swarms. They are species of short-horned grasshoppers that periodically form large populations in dense migrating groups, where individuals differ in several characteristics from those living separately.

When these locusts meet suitable environmental conditions, they become gregarious and start breeding abundantly. With their population becoming denser, they form swarms and keep moving across areas damaging the crops.
