Locusts are a type of grasshopper known for their ability to form large swarms. They can change their behavior and physical characteristics when their population density increases, leading to destructive swarming events. These swarms can travel long distances and consume vast amounts of crops, posing a significant threat to agriculture. Locusts are found in many parts of the world, particularly in Africa, Asia, and Australia. They are typically solitary but can become gregarious under certain conditions, leading to their swarming behavior. Effective management strategies are essential to control locust populations and minimize their impact on food security.
