Mermiria bivittata bivittata
Twostriped Slantfaced Grasshopper
Mermiria bivittata bivittata is a large, long-winged grasshopper widely distributed across North America, with its center of abundance in the tallgrass prairie. It is a specialist feeder on native grasses, reaching densities up to one adult per square yard in undisturbed habitat. Despite its potential as a pest due to high individual consumption rates, populations typically remain at low densities and rarely cause significant economic damage. The subspecies exhibits late hatching, relatively slow nymphal development, and strong flight capabilities.
