Morphological variation in six grasshopper species is examined. Statistics describing collections (adult males and females) made during July 1986 and July and August 1987 are given. Five of the species are characterized by long wings, and the sixth is wing-length dimorphic. Additional collections at several western Nebraska grassland sites were used to examine relationships between nymph population density and wing-length frequencies in adults. Coefficients of variation were also calculated to facilitate designs of future experiments.
