3D models and computational fluid dynamics simulations. Dorsal view of phasmid models with no (A), natural (B) and widened (C) ‘leaf-like’ abdominal expansions. Air velocity in the mid-sagittal plane (D–F), air velocity and streamlines in a horizontal transverse plane (G–I), pressure (relative to ambient air static pressure) and streamlines in the mid-sagittal plane (J–L) around the bodies of males with no (D, G, J), natural (E, H, K) and widened (F, I, L) abdominal expansions
