About Grasshoppers of the Western US
The Grasshoppers of the Western U.S. Lucid mobile app offers keys to identify both adult and pre-adult stages of many of the most commonly encountered grasshoppers in the western U.S. The adult key facilitates the identification of 76 species of adult grasshoppers. All species included are in the family Acrididae with the exception of one, Brachystola magna, which is in the family Romaleidae. See the keys page if you need help determining whether your specimen is an adult or a nymph. The Lucid mobile keys were created by USDA-APHIS-ITP through collaboration with the USDA-APHIS-PPQ-S&T CPHST Phoenix Lab, USDA-APHIS-PPQ Colorado SPHD Office, University of Nebraska at Lincoln, Chadron State College, and Identic Pty. Ltd. (Lucid).
The keys are designed for people with varying degrees of knowledge identifying rangeland grasshoppers, from the general enthusiast to research scientist. The species fact sheets include photos and drawings by Dr. Robert Pfadt from the University of Wyoming with additional photos by Mathew L. Brust from Chadron State College.
Key authors: Mathew Brust, Jim Thurman, Chris Reuter, Lonnie Black, Robert Quartarone, and Amanda Redford.
This Lucid mobile app is part of a complete identification tool released in 2014: Brust, Mathew, Jim Thurman, Chris Reuter, Lonnie Black, Robert Quartarone, and Amanda Redford. Grasshoppers of the Western U.S., Edition 4. USDA-APHIS-ITP. Fort Collins, Colorado.
