Head-body 97-112 mm, tail 32-42 mm, ear 9-10 mm, hindfoot 19-19 mm; weight averages 19 g. The Creeping Vole is one of the smallest species of Microtusin North America and has a very shorttail. Pelage is dense, soft, and sooty gray to yellowish brown on back; venter is dusky. Tail is indistinctly bicolored, and ears are small, blackish and lightly haired. Hindfeet have five plantar tubercles. Molars are small, M? has 2-3 closed triangles, M, has five closed triangles, and M, has three transverse loops.

Dry short-grass habitats in coniferous forests. Clearcut disturbed sites and areas where timber slash has been burned support higher densities of Creeping Voles because of the herbaceous-dominated vegetation.

Breeding of Creeping Volesis reportedly year-round but mostly in March— September. Gestation is ¢.23 days, and 4-5 litters with 3-4 young each are produced annually. Young are born in nests of dry grass placed in cavities under logs or in similarly protected sites.

. They are known to tunnel but not exclusively, and they often use aboveground runways. Home ranges are 0-05-0-38 ha for males and 0-04—0-23 ha for females; they decrease in size through summer. Densities have been reported as high as 138 ind/ha at the northern edge of the distribution in British Columbia, but much lower in the south.
