All movements are driven by variations on two general systems of proteins. Turning our attention to insects, one of the most obvious features of insects is that most of them are able to fly. The common names of insects reflect flight again and again, for examples, dragonflies, damselflies, houseflies, mayflies, stoneflies, fruitflies, hoverflies, butterflies. I am sure you can think of many more examples. All bespeak the point that most insects are fliers.
Flight bears on nearly every aspect of insect biology.
Foraging for food, searching for mates, escape from predators or fly swatters, avoiding harsh or unfavorable conditions, and locating egg-laying sites are just a few points of insect biology intimately connected to flight behavior. We first consider structures of insect flight muscles. In tubular muscles, fibrils are arranged radially about a column of sarcoplasm that contains several nuclei. Mitochondria are interspersed in the radial area of the muscle. Dragonflies feature this type of flight muscle structure.
