The state-of-the-art of insect flight research using advanced computational fluid dynamics tech-niques on supercomputers is reviewed, focusing mostly on the work of the present authors. We present a brief historical overview, discuss numerical challenges and introduce the governing model equations. Two opensource codes, one based on Fourier, the other based on wavelet representation, are succinctly presented anda mass-spring flexible wing model is described. Various illustrations of numerical simulations of flapping in-sects at low, intermediate and high Reynolds numbers are presented. The role of flexible wings, data-driven modeling and fluid–structure interaction issues are likewise discussed.
