Mearns's grasshopper mouse or the Chihuahuan grasshopper mouse (Onychomys arenicola) is a grasshopper mouse found in southwestern New Mexico, West Texas, and north-central Mexico. They are similar to Onychomys torridus, but differ in karyotype and size. This mouse is smaller in every regard except for the nasal length of the skull.[2]

They are found in semiarid habitat, prairie, and scrub. They feed largely on insects and other invertebrates, including scorpions. They also feed on small muroid rodents and pocket mice.
