This small mouse lives in grassland and riparian habitats and is active at night. Its tail is differently coloured above and below, while its coat and diet vary by place and season.
The tail is brown on top and grayish white underneath. It measures 73–117 mm and can be 10–50% longer than the head and body combined. Subspecies and regions show subtle coat differences.
It is active from shortly after sunset until sunrise. Diet varies by place and season; insects are often eaten in spring and summer, while seeds are a major food in autumn and winter.
