Grasshopper mice are unusual among rodents: despite the name, they’re mostly predators, hunting insects, scorpions, and even other mice, and they’re known for standing on their hind legs and giving a high thin howl to mark territory. Texas’s Chihuahuan grasshopper mouse records concentrate in Jeff Davis and Brewster counties, around the Davis Mountains and Big Bend, the Chihuahuan desert and grassland this species needs.
The 46 Texas records run highest in February and March, with 10 each against single digits every other month, though the most recent record dates to August 2021, so current activity in the state is harder to confirm. NatureServe ranks the species S4, Apparently Secure, in Texas, comfortable but not the top tier.
Only 3 of the 46 records come from iNaturalist, so almost everything known about this species in Texas still comes from specimen collections and targeted small-mammal surveys rather than casual sightings.
