What are mice with a black stripe on their back? - briefly

They belong to the genus Rhabdomys, known as striped mice, and are distinguished by a dark dorsal stripe running along the spine. The stripe serves as a primary visual cue for identifying this species among other field rodents.

What are mice with a black stripe on their back? - in detail

Rodents that exhibit a distinct black dorsal stripe belong primarily to two well‑documented groups: the striped field mouse (Apodemus agrarius) of Eurasia and the African striped mouse (Rhabdomys pumilio). Both species share a narrow, dark line running along the spine, but they differ in taxonomy, range, and ecological habits.

Apodemus agrarius is a member of the Muridae family, classified under the genus Apodemus. Adults measure 9–12 cm in head‑body length, with a tail of comparable length. The dorsal pelage is brownish‑gray, intersected by a narrow, sharply defined black stripe that extends from the occiput to the base of the tail. Ventral fur is pale, and the ears are relatively large. This mouse inhabits cultivated fields, grasslands, and riverbanks across eastern Europe, Siberia, Korea, and northern China. It is primarily nocturnal, foraging on seeds, insects, and occasional plant material. Breeding occurs in the warmer months; litters contain 4–7 young, which reach independence after three weeks.

Rhabdomys pumilio, commonly called the African striped mouse, resides in southern Africa’s savannas, shrublands, and agricultural margins. It measures 7–10 cm in body length, with a tail slightly shorter than the body. The coat is gray‑brown, crossed by a bold black stripe that may be flanked by lighter lateral stripes. The species displays a high degree of adaptability, exploiting seeds, arthropods, and nectar. It breeds throughout the year in favorable conditions, producing 2–5 offspring per litter. Socially, it forms small groups and exhibits territorial scent marking.

Key distinguishing features:

  • Taxonomic family: Muridae (Apodemus) vs. Muridae, subfamily Deomyinae (Rhabdomys)
  • Geographic distribution: Eurasian temperate zones vs. southern African regions
  • Habitat preference: Open fields and riparian zones vs. savanna and cultivated lands
  • Size: Slightly larger body in Apodemus agrarius
  • Social structure: Primarily solitary or loosely paired (A. agrarius) vs. small group living (R. pumilio)

Both rodents are of interest to researchers studying disease ecology, as they can serve as reservoirs for hantaviruses and other zoonotic pathogens. Their distinctive dorsal stripe aids field identification, facilitating population monitoring and ecological surveys.
