Southern
Grasshopper Mouse
Onychomys torridus
Body length: 3 1/2 - 4"
Diet: Insects, scorpions, other mice, lizards, and seeds
Grasshopper mice have been described as the wolves of the mouse world. Unlike
their seed-eating relatives, they are insectivorous and carnivorous - that is,
insect-eating and meat-eating. Although insects may form their principal food,
grasshopper mice also eat spiders, scorpions,
and lizards, and are legendary for killing and eating
other mice in captivity. At times when these foods are scarce, grasshopper mice
will also eat seeds.
To add to their most un-mouse-like nature, grasshopper mice "howl",
or call (like wolves) with a high-pitched whistle. This species is monogamous,
or faithful to one mate, and both parents care for the young. In appearance, grasshopper
mice are difficult to distinguish from other mice, having a typically small build,
gray-brown fur, and large ears. When captured, however, they emit a distinctive,
almost skunk-like smell. Grasshopper mice occur at Tonto National Monument in
areas north of the Visitor Center.
