  1. The analyses were conducted separately for G. fultoni (n = 120) and G. vernalis (n = 91). The response variables included head width, thorax length, hind femur length, and ovipositor length. The predictor variable was zone, and covariates were latitude, longitude, and elevation. Numbers in bold indicate significance at the level of 0.05.
