Desert Locust

The desert locust is a species of short-horned grasshopper native to the arid and semi-arid regions of Africa, the Middle East and parts of South Asia, notorious for its capacity to transform under crowded conditions from a solitary, relatively harmless insect into a highly mobile, gregarious swarming form that can travel across vast distances in search of food. Triggered by increased population density, often following periods of favorable rain that boost breeding success, individual locusts change in color, behavior and even body proportions, aggregating into swarms that can contain many billions of insects and strip crops and vegetation bare across huge areas within a very short time. A single large swarm can consume as much food in a day as tens of thousands of people, and historically severe desert locust plagues have caused devastating famine and economic damage across affected regions of Africa and Asia. Modern locust control relies heavily on early detection of breeding conditions and targeted aerial spraying to prevent solitary populations from reaching the density needed to trigger a full swarming outbreak.
