Humans throughout history have looked to biology for engineering inspiration. Perhaps one of the most famous examples is looking to birds to inspire a vehicle capable of flight. While Daedalus's wings of wax and feathers may have only existed in Greek mythology, Leonardo da Vinci's sketches of prospective flying machines and their resemblance to birds are well documented. This article focuses on the problem of interception, focusing on insects, specifically dragonflies, for inspiration. A number of recent studies have characterized the hunting behaviors of animals, reporting on a range of animals, including dragonflies, bats, hawks, peregrine falcons, and robber flies that demonstrate behaviors best fit by proportional navigation guidance law. The use of proportional navigation by animals is particularly interesting because it is also used by modern missile systems, raising the question of what can be learned from understanding how an insect implements this guidance law. The question of how animals implement proportional navigation remains unanswered, however, as it requires maneuvering to maintain a constant angle between the animal's line-of-sight to its prey and an external reference.
