Locust may be solitary of gregarious. It depends upon ______?

Locusts switch between solitary and gregarious behavior depending on food conditions. When food is scarce, locusts live solitary lives,分散 feeding to avoid competition. However, when food is abundant, they congregate in large numbers, forming swarms, which is the gregarious phase. This change is triggered by increased population density and the need to access plentiful food sources.
