Identification
Very similar to Hesperotettix viridis, especially the subspecies pratensis, but with very short wings that are usually separated along the middle when folded. This may only be a subspecies of H. viridis, but H. viridis ssp. viridis or ssp. nevadensis often occur near to H. curtipennis (in different habitats or on different plants), and H. curtipennis remains distinct.

It is possible that H. viridis and the "subspecies" pratensis are really distinct species (they often occur together or near to one another, and seem to remain distinct). In which case H. curtipennis may be a short-winged western mountain variant of H. pratensis, replacing it geographically. The population limits of these very similar insects definitely needs further study.

No other species is likely to be confused with H. curtipennis.
