Grasshoppers

Counting adult grasshoppers to estimate adult densities in an area in late summer (when grasshoppers are laying eggs) helps estimate the number of eggs overwintering and to forecast the risk of grasshoppers being at problem levels in the next growing season. To count fully winged adult grasshoppers, sites should be surveyed between August 1st and September 1st.
