Oldfield Mice are found in northern and central Florida, in areas with sandy soil, and on grass covered beach dunes. They live in burrows, which they dig themselves. The burrows are usually about three feet deep with one or two chambers at the end, and each mouse may have as many as 20 burrows in its home range.

The species is unusual in that males and females have strong pair bonds and cooperate to raise the young. Females can give birth to a new litter every 30 days.

Oldfield mice eat seeds, acorns, beetles and ants.
