The meadow jumping mouse has a long (four and one‐half to six inches) tail. The top of the tail is the same color as the back while the bottom of the tail is white.

The meadow jumping mouse may be found statewide in Illinois. This rodent lives in moist areas in ﬁelds, woods and along streams, ponds and marshes. It eats seeds. When this mouse is disturbed, it will move in a series of jumps. It can swim. The meadow jumping mouse hibernates during the winter, usually entering hibernation in late September or October. It emerges again in late April or May. Mating probably occurs twice a year, once in spring and once in fall. The litter size varies between two and nine. Young are helpless at birth but develop rapidly. They are able to live on their own in about four weeks.
