A migratory locust is a remarkable insect known for its ability to undergo mass migrations and cause significant agricultural damage. As a member of the grasshopper family, the migratory locust shares similar physical characteristics, including a long, slender body and powerful hind legs for jumping.

During favorable environmental conditions, such as abundant food and suitable breeding sites, populations of migratory locusts can rapidly increase and form dense swarms that can cover vast distances.
