Maximowicz's vole is one of the largest voles in the genus '' Microtus''. Adults grow to a head-and-body length of with a tail length of . The fur on the back is dark brownish-black with ochre specks, and the flanks are paler brown, blending gradually into the greyish-white underparts. The upper sides of the hands and feet are whitish-brown. The tail is either uniform dark brown or bicoloured, with the upper side dark brown and the underside white. Its scientific and common names commemorate the prominent Russian botanist Karl Maximovich, who was curator of the herbarium at the Saint Petersburg Botanical Garden at the time the vole was described by Leopold von Schrenck.Reisen und Forsch., in Säugeth.

Behaviour

Maximowicz's vole is most active early in the morning and shortly before nightfall when it emerges from its burrow to feed on grasses and other plant material. The entrance to the burrow has a spoil heap which may be up to in diameter and in height. The tunnel itself is quite short and terminates in a nest chamber some in diameter and high. Other side chambers are used for storing roots and bulbs for winter food. Not much is known of the breeding habits of Maximowicz's vole but females have been reported as carrying seven and nine embryos.


Status

Maximowicz's vole has a very wide range. It is common in much of that range and faces no particular identified threats, so the International Union for Conservation of Nature has assessed its conservation status as being of " least concern".
