Both sexes of these locusts transmit poultry tapeworms and also parasites that mature in quail, turkeys, and guinea fowl. The similar Rocky Mountain Grasshopper 1 1/8-1 1/2", is brownish above with dark markings. It reached plague proportions in the West before 1900, but now is probably extinct. The "Grasshopper Glacier" near Cooke, Montana, contains millions of embedded Rocky Mountain Grasshoppers, presumably from swarms that settled on the glacier and froze. |
