Grasshopper Cross
Union County · South Dakota
Erected by Regina Bernard and State Historical Society, 1966
The insect behind Father Boucher's pilgrimage was the Rocky Mountain locust, Melanoplus spretus, and its swarms of 1873 to 1877 did some $200 million in crop damage across the plains. One swarm reported in 1875 was estimated at 198,000 square miles and about 12.5 trillion insects. Within three decades the species was gone; the last specimens were collected in Manitoba in 1902 and Colorado in 1904. Entomologist Jeffrey Lockwood traced the collapse to settlers plowing, irrigating and grazing the Rocky Mountain river valleys where it laid its eggs.
