The term "locust" refers to any one of several species in the grasshopper family Acrididae
that, when their population reaches a certain tipping point within a certain area, will suddenly abandon a solitary lifestyle and become what scientists refer to as "gregarious," which is a polite term for "ravenous swarm of rapidly breeding insects that gobbles up crops for miles around.
Within the orthopterans, the family Acrididae

Apart from the aforementioned writings of Vickery, Rehn and Carbonell, very little has been written about the biogeographic origins of these subfamilies, individually or as a group--or indeed, of the family Acrididae
