Abstract
This paper describes the three-dimensional observation of morphology of flight muscles in some kinds of winged insects such as bees, dragonflies, and cicadae. In the 3-D observation of flight muscles, sequential sections through thoraces are sliced at the thickness of 30μm by the rotating knife and taken photos by camera with three-dimensional internal structure microscope automatically and repeatedly. Moreover, the 3-D images can be reconstructed by a computer based on the digital data after recording. Therefore, it is possible to observe any sections of thoraces, which have not actually been slices. From the 3-D observation, it is confirmed that the winged insects can be classified into three groups at least by the differences of morphology of flight muscles.
