Throughout the 1920s and especially the 1930s the Great Plains were hit by grasshopper invasions of varying intensity. Montana, Kansas and Nebraska all reported grasshopper damage to crops in the 1920s. The photographer, South Dakota State University agronomist Joseph G. Hutton, took this picture of a Douglas County sweet clover haystack that has been partially eaten away. The photographer did not specify what had eaten the haystack, but it was may have been eaten away by grasshoppers or other insects. The photograph was taken July 23, 1923. (1981:071:0040)
