The members of the genus Trimerotropis are brightly colored and often noisy. Thus, they are readily observed and frequently collected. They never reach the levels of abundance nor inflict the level of damage observed among such grasshoppers as the Melanoplines. The indications of abundance in this section of the key are relative to other Trimerotropis spp., not other genera.
A Wings colorless or tinged with blue, brown, green or pink.
A' Wings with discs yellow (may be pale yellow); dark bands on wings present.
