Though it is commonly called a Mormon Cricket, your insect is actually a large, flightless Katydid. According to BugGuide: “Though flightless, this species can form migratory swarms or “bands” that travel on foot, eating almost anything (both plant and sometimes small animal) in their paths, and have been significantly destructive to rangeland and crops at times. Swarming occurs primarily in the Wyoming Basin, Colorado Plateaus, Great Basin, and Columbia Plateau. In the Sierras, Rockies, and other higher mountain areas, and on the northern Great Plains, individuals average smaller, are usually non-migratory, and coloring is commonly of lighter colors (often tan or green). Individuals in bands are most commonly of a deep brown, often nearly black color.” The ovipositor indicates your individual is a female.
