Acrididea

Acrididea including the Acridomorpha^[3] is an infraorder of insects that describe the grasshoppers (thus also locusts) and ground-hoppers. It contains a large majority of species in the suborder Caelifera and the taxon Acridomorpha may also be used, which excludes the Tetrigoidea.^[4] Both names are derived from older texts, such as Imms,^[5] which placed the "short-horned grasshoppers" and locusts at the family level (Acrididae). The study of grasshopper species is called acridology.
