The morphology and the innervation of the main wing depressor muscles have been studied. The motoneurones to these muscles have dendrites ipsilateral to the muscle they innervate and located in the dorsal neuropile. With the exception of one motoneurone, to the dorsal longitudinal muscle, all motoneurone cell bodies are ipsilateral to the muscle they innervate. The morphologies of individual cobalt stained motoneurones are described. Flight motoneurones to wing depressor muscles are not electrically or chemically coupled to one another.

Key words: Moth, flight, motoneurones
