The complete county distribution, spread across 2 Texas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Desert pocket mice turn up almost entirely through trapping surveys, not photographs: only two of the 15 Texas records come from iNaturalist, with the rest logged as GBIF-linked museum and survey data. That split makes sense for a small nocturnal rodent that spends the day underground and rarely crosses paths with a phone camera. Big Bend National Park, in the driest, rockiest corner of West Texas’ Chihuahuan Desert, accounts for 13 of them, and El Paso County adds one more.

The records all fall between May and September, 8 in May, 6 in July, and 1 in September, too few to read as a real season; they more likely mark when trapping crews were in the field. The most recent listed observation dates to 2022, a reminder that most of what’s known about this species in Texas comes from periodic survey work rather than ongoing citizen reporting. It sits in the occasional bucket among Texas mammals, but that reflects trap effort at one well-studied desert park, not how widely the species is actually distributed across the state.
