Heliastus

As band-winged grasshoppers (subfamily Oedipodinae), members of Heliastus possess hindwings with distinct color patterns—typically bands or patches of contrasting color—that are concealed beneath narrow, mottled forewings when at rest. This wing-folding mechanism serves as camouflage. Specific diagnostic characters for distinguishing Heliastus from related genera within the tribe Hippiscini are not documented in the provided sources.

Species in this genus occupy arid and semi-arid environments. Heliastus benjamini has been observed in canyon habitats. The common name of H. subroseus (rose-wing beach grasshopper) suggests coastal or sandy habitat associations. The distribution records indicate occupancy of desert washes, rangeland, and similar xeric habitats.

Recorded from: Arizona, Colorado (United States); Mexico; Costa Rica; Colombia; northern Chile. The genus spans from the southwestern United States through Central America and into western South America.

Heliastus benjamini has been described as a "truly desert species." Like other band-winged grasshoppers, individuals likely rely on camouflage when at rest, with brightly patterned hindwings exposed only during flight.

• CibolacrisAlso contains small, cryptic grasshoppers of arid southwestern habitats; historically confused with band-winged grasshoppers but now placed in subfamily Gomphocerinae rather than Oedipodinae.
• TrimerotropisAnother genus of band-winged grasshoppers (Oedipodinae) with similar wing-concealment behavior and arid-land distribution; differs in specific wing pattern and body proportions.
• LactistaSmall band-winged grasshopper genus with yellow-and-black hindwing pattern; Heliastus species may overlap in range and habitat with Lactista aztecus in the southwestern United States and Mexico.
