Southern Grasshopper Mouse
Although Southern grasshopper mice protect crops from insects and rodents, they will also feast upon crops if their usual prey becomes scarce.
Largely due to their ferocity and appetite, southern grasshopper mice are considered beneficial by farmers and others because they eat potentially harmful insects. They help farmers by eating a large number of insects and rodents that would otherwise destroy crops.
Although southern grasshopper mice are mainly carnivorous, they do eat the same crops they normally help defend if their usual prey, insects and small vertebrates, become scarce.
