Locusts belong to a large group of orthopteroid insects in the superfamily Acridoidea, with most in the family Acrididae. This family also includes many grasshoppers. Locusts are similar to grasshoppers in their morphology and differ from them only in their behaviour in which they show a strong tendency to group together and become gregarious, and then to migrate in large swarms. The behavioural distinction is not complete, for there is really a spectrum of types; at one extreme are species that readily become gregarious and swarm—typical locusts, and at the other are those that always live solitary lives, never aggregate and never swarm—typical grasshoppers. There are species of locusts that live for many generations without aggregating and similarly, there are species of grasshoppers that may aggregate but do not migrate in swarms. Locusts are therefore those species that aggregate and swarm more commonly and grasshoppers are those which rarely aggregate.
