MORENO, C.A.*; TU, M.S.; DANIEL, T.L.: Visual-motor feedback in the tracking behavior of hovering Manduca sexta. Insight into the complex interplay of sensory information, musculoskeletal mechanics, and aerodynamic forces is critical for understanding the fundamental determinants and limits of insect flight performance. While feeding at flowers in the wind, hovering hawkmoths must track a moving […]

Sane, S.P.*; Dickinson, M.H.: Unsteady aerodynamic forces are important for production of force moments by flapping wings. Insects use aerodynamic forces not only to stay in air, but also to steer and maneuver. Through changes in wing kinematics, insects can finely control the pitch, roll and yaw moments around their body and thus maneuver. In […]

COMBES, S.A.*; TRIMBLE, A.C.; DANIEL, T.L.: Spatial profiles of wing stiffness in hawkmoths and dragonflies Insect flight performance depends strongly on the dynamic geometry of wings. The curvature of the trailing edge, in particular, is a crucial determinant of aerodynamic force generation. In insects, wing curvature results from the instantaneous interaction between aerodynamic forces and […]

BIRCH, J.M.*; DICKINSON, M.H.: Dynamic stall of a flapping appendage in the absence of a spiral vortex Recent studies of insect flight describe how dynamic stall and the formation of a leading edge vortex generate large lift forces for insects. This leading edge vortex, along with forces generated through rotation and wake capture, accounts for […]
