The grasshopper subfamily Acridinae, sometimes called silent slant-faced grasshoppers, belong of the large family Acrididae in the Orthoptera: Caelifera.
Description
In appearance, the species are often similar to those of the subfamily Gomphocerinae, with whom they share a slanted face. However Acridinae differ from Gomphocerinae in that they lack stridulatory pegs on their hind legs and thus, as the common name suggests, do not make sounds. The antennae of this species is flattened and sword-like, a trait also shared with some gomphocerines and also with the spurthroated grasshoppers (subfamily Cyrtacanthacridinae). They lack the posternal spine seen in the spurthroated grasshoppers and lubber grasshoppers (subfamily Romaleinae). Hind wings in this species range from nearly colorless to colorless.
