This work is a synthesis of our current understanding of the mechanics,
aerodynamics and visually mediated control of dragonfly and damselfly flight,
with the addition of new experimental and computational data in several key
areas. These are: the diversity of dragonfly wing morphologies, the aerodynamics
of gliding flight, force generation in flapping flight, aerodynamic efficiency,
comparative flight performance and pursuit strategies during predatory and
territorial flights. New data are set in context by brief reviews covering
anatomy at several scales, insect aerodynamics, neuromechanics and behaviour. We
achieve a new perspective by means of a diverse range of techniques, including
laser-line mapping of wing topographies, computational fluid dynamics simulations
of finely detailed wing geometries, quantitative imaging using particle image
velocimetry of on-wing and wake flow patterns, classical aerodynamic theory,
photography in the field, infrared motion capture and multi-camera optical
tracking of free flight trajectories in laboratory environments. Our
comprehensive approach enables a novel synthesis of datasets and subfields that
integrates many aspects of flight from the neurobiology of the compound eye,
through the aeromechanical interface with the surrounding fluid, to flight
performance under cruising and higher-energy behavioural modes.This article is
part of the themed issue 'Moving in a moving medium: new perspectives on flight'.
