This website provides one of the most comprehensive sources of information on the biology, ecology, identification and management of grasshoppers and Mormon crickets in North America. It also contains information on non-target effects, current survey information, and decision support software. The site was produced by the USDA-ARS-Northern Plains Agricultural Research Lab in Sidney, Montana, and several collaborators.

Site Highlights.
Grasshopper Identification Guides and Species Fact Sheets  Several identification guides, keys and a naturalist's guide are provided to help identify grasshopper species throughout North America and to provide information on the biology and economic importance of individual species.  Fact sheets, with photographs, for 60 common species.


Field Guide to Common Western Grasshoppers  An overview of grasshopper biology, ecology, anatomy, life cycles and surveys.


Grazing Management and Grasshoppers  Grazing management methods to help reduce grasshopper outbreaks.


Chemical Control Methods  New aerial and ground based techniques (RAATs) for reducing pesticide application rates, costs, and environmental concerns.

Electronic Key for Common Adult Grasshoppers of the Western U.S.  This new key from USDA-APHIS is a powerful yet simple interactive identification system that allows users to identify 70 common adult grasshoppers.
