What is the fastest flying insect in the world?

The fastest flying insect in the world is the dragonfly. Its speed, agility, and ability to change direction rapidly make it the standout aerial hunter among insects.

The title is generally associated with the southern giant darner, an Australian dragonfly sometimes identified by its scientific name, Austrophlebia costalis. Historical measurements recorded a dragonfly traveling at about 98.6 kilometers per hour, although that figure measured ground speed. More conservative measurements of actual airspeed are closer to 58 kilometers per hour.

Dragonflies achieve this performance with two pairs of independently controlled wings. Unlike many insects, they can hover, fly backward, stop suddenly, and pivot in midair. Their huge compound eyes also provide an exceptionally broad field of view, helping them track mosquitoes, flies, and other small flying prey.

The answer is sometimes confused with the fastest land-running insect or with the fastest animal overall. The exact record depends on whether researchers measure ground speed, airspeed, or a short burst, but “dragonfly” remains the standard general-knowledge answer.
