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