There exists considerable inter- and intra-population variation in the timing of the induction of egg diapause and the stage at which diapause occurs in species of grasshopper that have an embryonic diapause and a broad geographic range, such as Melanoplus sanguinipes. An individual-based grasshopper population model was used to examine the evolution of these diapause traits, and the results compared to mathematical models and field data.
