GRASSHOPPERS OF NEW MEXICO

PREFACE

Grasshoppers of New Mexico Contents

This manual was prepared to catalog known grasshopper fauna for New Mexico and to aid in identification of various species known or suspected to occur in the state. As an identification manual, it can define faunal compositions and thus be used to identify potential grasshopper problem spots, as well as provide information that will prevent costly insecticidal control programs for non-economic species. We have included general distribution data, hosts, common names, adult occurrence in time, and any notes that might help identify and determine economic status of a given species. In addition, there is a discussion of the morphology and biology (Lightfoot) and economic and historic aspects (Sutherland) of New Mexico grasshoppers.

The distribution maps, while not complete, should give the reader an indication of the grasshoppers likely to be encountered in a particular area. The keys are based on those of Ball et al. (1942), Helfer (1953), Wallace (1955), Dirsh (1974), Capinera and Sechrist (1982b), and Otte (1981, 1984), as well as modifications and original couplets by Richman, Lightfoot, and Ferguson. We hope that this work based on adult grasshoppers will be useful not only for the state of New Mexico, but also for eastern Arizona, southern Colorado, western Texas, and northern Chihuahua, Mexico.
