How insect flight steering muscles work.

Two opposing groups of power muscles drive the insect's wings, while the force is funneled to the wing by a very intricate hinge system. In recent PLOS Biology research, the specifics and partially novel function of several of these steering muscles and their tendons have been revealed. Graham Taylor and colleagues' latest research uses time-resolved X-ray microtomography to get a three-dimensional view of the blowfly wingbeat. Differential wingbeat amplitude on the left and right wing, which is mediated by muscular control of the hinge pieces to mechanically prevent the wing stroke and absorption of labor by steering muscles on one of the sides, is the key to asymmetric power output. This very promising line of work will help to reveal the complete picture of a fly's flight motor.

Wing structure and neural encoding jointly determine sensing strategies in insect flight.

In many flying insects, strain-sensitive neurons on the wings provide rapid feedback that is essential for stable flight control. Although the effects of wing structure on aerodynamic results have been well documented, sensing by wing structure is largely unexplored. We show how the wing's structural properties and encoding by mechanosensory neurons work together to determine optimal sensing tactics and performance. We investigate how neural sensors can be placed on a flapping wing to track body rotation about various axes, using a computational wing model with varying flexural stiffness. Both the wing base and the wing tip are highly concentrated, and they change quickly as a result of both wing stiffness and neural threshold. The evidence of wing structure and neural encoding characteristics has highlighted the importance of knowing both in the context of their joint evolution.
