HIGH wingbeat frequencies are required for flight in many insects, and have led to striking specialisations1. The thorax and wings form a resonant system whose oscillation is sustained by alternating contractions of antagonistic muscles. The action of these flight muscles is to produce only a small-amplitude deformation of the thorax, mechanically amplified into wing movements. The muscles are diverse in arrangement1 and ultrastructure2. In several insect orders, they are of a characteristic… CONTINUE READING
