Grasshopper populations increased dramatically in Montana from 2007 to 2010, from one million acres with more than 15 grasshoppers per square yard in 2007, to 17 million acres with more than 15 grasshoppers per square yard in 2010. However, crop and rangeland damage has been somewhat moderated by the cool and wet spring weather of 2010 and 2011.
