Predatory behavior and effect of prey size of the praying mantis,Tenodera aridifolia, was investigated using three-dimensional prey models. Parameters of prey such as width, length, shape (length/width), area (width×length) and volume were investigated for effects on Watch and Attack responses. Regression analyses suggest that volume is the most important variable in prey recognition. This behavioral trait is considered adaptive, since prey volume is the most reliable measurement for the energy content of the prey.
