how fast can a dragonfly fly?

Dragonfly Speed Compared

These values do not describe every dragonfly. The order Odonata includes species with very different body sizes, wing shapes, habitats and flight behaviors. A small dragonfly moving through dense vegetation should not be expected to match the speed of a large hawker flying through open air.

Can Dragonflies Really Fly at 60 MPH?

The evidence does not support presenting 60 mph as a dragonfly’s verified airspeed through still air.

The famous figure comes from a 1917 observation of the Australian dragonfly Austrophlebia costalis. It was reported moving at 98.6 km/h, or 61.3 mph, over a distance of approximately 73–82 meters.

However, Guinness World Records identifies that measurement as ground velocity. Ground velocity measures movement relative to the land and can be increased by a tailwind. It is not the same as the speed generated by the insect relative to the surrounding air.

Guinness gives 58 km/h, or 36 mph, as the maximum short-burst airspeed for Austrophlebia costalis. That is the more defensible figure to use when discussing the species’ exceptional flight performance.

Why Do Sources Give Different Dragonfly Speeds?

Conflicting speed figures usually result from differences in the species, flight behavior and measurement method being discussed.

1. Different species have different flight capabilities

“Dragonfly” does not refer to one animal with one fixed speed. Large hawkers, skimmers and other dragonfly groups differ in body mass, muscle capacity, wing loading and preferred habitat.

The 36 mph Guinness figure applies specifically to the southern giant darner, Austrophlebia costalis. It should not be presented as the everyday speed of all dragonflies.

2. Maximum speed is different from normal flight speed

A dragonfly may accelerate sharply while chasing prey, avoiding danger, competing with another dragonfly or launching from a perch. Such a burst is not equivalent to a maintainable cruising speed.

Guinness explicitly separates a highest maintainable airspeed of about 24 mph from the 36 mph short-burst maximum recorded for the Australian species.

3. Wind can change the observed ground speed

A tailwind increases ground speed, while a headwind reduces it. Historical observations made without simultaneous wind measurements can therefore overestimate or underestimate the insect’s self-generated speed.

4. Small flying insects are difficult to measure

Dragonflies do not normally follow a long, level and perfectly straight flight path. They accelerate, brake, turn, climb and descend rapidly. Modern studies use calibrated high-speed cameras, reconstructed three-dimensional trajectories and aerodynamic models to analyze these movements.

5. Popular fact pages may simplify the evidence

One Smithsonian “Incredible Insects” page states that dragonflies travel at 35 mph. A separate Smithsonian insect-flight information sheet identifies sphinx moths at 33 mph as the fastest insect flight in its summary.

This difference illustrates why the title “fastest flying insect” depends on the source, species, definition and quality of the underlying measurement. The safest wording is that dragonflies are among the fastest and most capable insect fliers.

Are Dragonflies the Fastest Flying Insects?

Under the current Guinness World Records classification, Austrophlebia costalis holds the fastest-flying-insect record, with a maximum airspeed of 58 km/h or 36 mph during short bursts.

Broader scientific comparisons are more complicated. Only a limited selection of insect species has been measured under comparable conditions. Some older claims about extremely fast horseflies and bot flies were based on estimates that modern researchers consider unreliable.

Dragonflies can reasonably be described as among the world’s fastest flying insects, but every speed claim should identify whether it refers to sustained airspeed, a short burst or wind-assisted ground speed.

How Do Dragonflies Fly So Fast?

A dragonfly’s flight performance comes from a combination of four-wing control, strong flight muscles, rapid sensory processing and the ability to alter its body and wing movements from one maneuver to the next.

Four separately controlled wings

Dragonflies have a pair of forewings and a pair of hindwings. The two pairs can be moved with different timing rather than functioning as one permanently linked surface.

By changing the phase relationship between the forewings and hindwings, a dragonfly can adjust the balance between lift, forward thrust, stability and maneuverability.

Wing phasing can affect aerodynamic efficiency

A study published in the Journal of the Royal Society Interface found that appropriate forewing–hindwing phasing could reduce aerodynamic power requirements by as much as 22 percent in the modeled conditions, compared with relying on a single pair of wings.

This does not mean that one wing pattern is always best. Dragonflies adjust wing timing according to whether they are hovering, accelerating, cruising or turning.

Flexible control of stroke angle and wing rotation

Dragonfly wings do more than flap vertically. During each wingbeat, the insect changes stroke direction, angle of attack and wing rotation. These movements interact with vortices and other unsteady airflow structures around the wings.

The resulting airflow is more complex than the steady airflow over a fixed airplane wing. This is why simple airplane or propeller comparisons do not adequately explain dragonfly flight.

Can Dragonflies Fly Backward?

Yes. Backward flight in dragonflies has been recorded and studied using high-speed video and aerodynamic analysis.

In a 2018 study published in the Journal of the Royal Society Interface, researchers examined a dragonfly accelerating backward along a flight path inclined relative to the horizontal. The insect changed its body angle and wing kinematics to generate the forces required for reverse movement.

Dragonflies can also perform several other movements that many insects cannot execute with the same degree of control:

• Hovering in a nearly fixed position
• Flying forward and backward
• Moving sideways
• Climbing or descending rapidly
• Gliding between periods of powered flight
• Turning sharply while tracking another insect

Speed Is Only Part of a Dragonfly’s Hunting Ability

Dragonflies catch other insects in the air, but successful hunting depends on more than simply flying faster than the prey.

A 2015 study in Nature tracked the head and body orientation of dragonflies during prey interception. The researchers found evidence that the insects used predictive internal models of their own body dynamics and the prey’s movement.

The dragonfly’s head continuously tracked the prey’s angular position, while body movements aligned the insect with an interception path. Vision was also used to respond when the prey moved unexpectedly.

This means a dragonfly does not always fly directly toward the prey’s current position. It can steer toward a point where the prey is likely to be, reducing the need for an inefficient tail chase.

What did laboratory hunting studies find?

A study published in the Journal of Experimental Biology followed nine dragonflies feeding on fruit flies over thousands of predation trials. Median capture-success rates among the individuals ranged from 0.83 to 0.95, or approximately 83–95 percent.

The result demonstrates highly effective aerial predation under the study conditions. It should not be interpreted as proof that every dragonfly catches every type of prey at the same rate in the wild.

What Determines a Dragonfly’s Flight Speed?

Species and body size

Larger, strongly built dragonflies may be capable of higher forward speeds than smaller species, although size alone does not determine performance. Wing geometry, muscle capacity and behavior also matter.

Wing shape and condition

Wing area, shape, stiffness, flexibility and damage can influence lift, drag and maneuverability. Research on dragonfly wing damage has found that damage can reduce flight performance and predation success.

Flight purpose

A territorial chase, prey interception, migration flight and slow patrol require different combinations of speed, endurance and maneuverability.

Temperature and weather

Environmental conditions affect insect flight. Wind changes ground speed, while temperature can influence muscle performance and the amount of time a dragonfly remains active.

Measurement method

Results from a short timed observation, a wind tunnel, a high-speed camera system and a three-dimensional free-flight study are not automatically interchangeable.

Final Answer

A large dragonfly may sustain approximately 23–24 mph and reach about 35–36 mph during an exceptional short burst.

The commonly repeated 60 mph claim is based on a historical ground-speed observation that could have included wind assistance. It should not be used as the dragonfly’s confirmed airspeed.

Dragonflies are remarkable not because they continuously fly at one extreme speed, but because they combine speed with hovering, backward flight, rapid acceleration, tight turns and predictive interception of moving prey.
