Mormon crickets (Anabrus simplex) are flightless North American shield-backed katydids that exist with a broad range of phenotypic variation including coloration, body size, movement behavior, and male calling behavior. Population types of Mormon crickets are classified as band-forming, non-band-forming, or intermediate based on estimated population density and movement behavior. Despite marked differences in morphology and behavior, these population types are still considered the same species although there is some evidence suggesting that they are genetically distinct (Bailey et al 2005). Mormon cricket morphology has been systematically described in terms of allometric, or size-correlated differences in shape between populations of Mormon crickets. The patterns of relationships between morphological characters have also been examined using morphological integration to see how they have changed over evolutionary time. Twenty-three morphological features of Mormon crickets collected from five populations in 2008 were measured and compared to the geometric mean for each individual. Shape differences by sex and by population type were tested for significance using two-way ANOVA. Principal component analysis of the covariance matrices was employed for data reduction and to explore the interactions between characters among BF and NBF Mormon crickets in terms of variance explained by size and shape versus shape alone. Correlation analysis was employed to test the relationships between morphological characters and movement patterns. Seven hypotheses of differences in covariation structure, or integration, were tested by constructing correlation matrices of the morphological variables and subjecting them to matrix correlations and Mantel tests. Integration patterns were discussed in terms of shape differences in morphology, local ecological conditions, and selection pressures by population.
