description Migratory Locust Overview
The Migratory Locust (Locusta migratoria) is a species of insect found across a vast geographical range that includes Europe, Africa, Asia, and Australia. It is monitored heavily by agricultural agencies for its ability to alter its behavior and morphology, shifting from a solitary phase to a highly destructive gregarious phase when population densities increase. In the gregarious phase, these grasshoppers form massive swarms capable of traveling long distances and consuming vast quantities of vegetation. Entomologists study the species to predict and prevent severe agricultural devastation.

The species has the ability to alter its behavior and morphology, shifting from a solitary phase to a gregarious phase. When forced into close contact due to limited resources, their serotonin levels spike, triggering them to swarm.
Why are agricultural agencies concerned about the Migratory Locust?
