The Taiwan field mouse, also called Formosan wood mouse (Apodemus semotus), is a species of rodent in the family Muridae. It is found only in Taiwan. The Taiwan field mouse is primarily distributed in the montane region between 1,400 to 3,000 m. [1] They inhabit various habitat types, such as natural or planted forests, grasslands, farms, and campsites, and are omnivorous feeding on plants, insects and fungi. [2]

Based on morphological measurements, it has been suggested that the Taiwan field mouse is not different from the South China field mouse (Apodemus draco), and should not be considered as a separate species.[3]

The Taiwan field mouse is sexually dimorphic, with male generally larger than females (male: 25.6 ± 0.5 g; female: 23.8 ± 0.5 g[4]). Mark-capture-recapture data suggest that their life span may be less than 1 year.[5]
