What Do Baby Dragonflies Look Like?
Baby dragonflies are aquatic predators called nymphs or naiads. Instead of looking like tiny winged dragonflies, they usually have muted brown, olive or green bodies, six jointed legs, large eyes, a segmented abdomen and a remarkable extendable mouthpart folded beneath the head.

What does a baby dragonfly look like? A baby dragonfly normally looks like a compact underwater insect rather than a miniature adult. It has six legs, large compound eyes, a broad or elongated segmented abdomen, short antennae and no functional wings. Older nymphs have wing pads on their backs. The easiest feature to miss is the hinged lower lip, or labium, which folds beneath the head and shoots forward to capture prey. Unlike most damselfly nymphs, dragonfly nymphs do not have three leaf-shaped tail gills.
They live underwater
Most dragonfly species spend their immature stages in ponds, lakes, marshes, wetlands or streams.
They are active predators
Their extendable labium captures aquatic insects, crustaceans and other appropriately sized animals.
They have no pupal stage
A mature nymph leaves the water and transforms directly into a winged adult during its final molt.
What Does a Dragonfly Nymph Look Like?
Dragonfly nymphs vary considerably because the suborder Anisoptera contains many species adapted to different freshwater habitats. Some are long-legged and streamlined, while others are broad, flattened or heavily camouflaged. Their overall shape can resemble a small, wingless insect, a squat aquatic beetle or even a spider-like creature walking along the bottom.
Despite these differences, most dragonfly nymphs share several recognizable features. Government field guides describe them as aquatic insects with six jointed legs, large eyes, a segmented abdomen, developing wing pads and no external leaflike gills.[1]
- Color: commonly brown, olive, gray, tan or green, often with mottling that matches mud, stones, leaves or aquatic plants.
- Body shape: elongated in some hunting species and broader or rounder in species that hide in bottom sediment.
- Eyes: large compound eyes positioned on the sides or upper surface of the head.
- Legs: six long, jointed legs used for walking, climbing, holding position and sometimes sensing nearby movement.
- Wing pads: small flattened structures on the thorax that become more prominent as the nymph approaches its final molt.
- Abdominal tip: usually ends in several short pointed appendages rather than three broad leaflike tails.
They are not miniature adult dragonflies
A newly hatched dragonfly has no functional wings and does not fly. Dragonflies undergo incomplete metamorphosis, so there is no caterpillar-like larva followed by a pupa. Instead, the aquatic nymph grows through repeated molts and changes directly into a winged adult during the final molt.
Key Parts of a Baby Dragonfly
Large compound eyes
Vision is especially important to nymphs that hunt among submerged vegetation. Their eyes are already prominent, although the proportions and placement vary among families. Burrowing species may rely more heavily on touch, vibration and chemical cues when concealed in sediment.
Six jointed legs
Like all insects, dragonfly nymphs have three pairs of legs attached to the thorax. The legs may be relatively long and slender in vegetation-dwelling hunters or shorter and more robust in species that crawl or burrow.
Developing wing pads
Young nymphs do not have visible adult wings. As they grow, flattened wing pads appear on the upper surface of the thorax. These pads enlarge during later instars and contain the developing wings that will expand after the final molt.
A folded predatory labium
The most specialized feature is the prehensile labium, a modified lower lip folded beneath the head. When prey comes within range, the labium extends rapidly, grips the animal and pulls it toward the mandibles.
How Big Are Baby Dragonflies?
There is no single standard size. A newly hatched stage may be only a few millimeters long, while a late-stage nymph of a large species may measure several centimeters.
The Missouri Department of Conservation gives a broad North American larval range of approximately ¼ to 2½ inches, or about 6 to 64 millimeters, depending on species and age.[1] The University of Florida also notes that some dragonfly naiads can reach approximately 5 centimeters.[3]
Size alone is not enough for identification
A small individual may be an early instar of a large species, while a fully grown nymph of another species may remain comparatively small. Body shape, wing pads, mouthparts, abdominal spines and terminal appendages are more useful when identifying a specimen.
Dragonfly Nymph vs. Damselfly Nymph
Dragonflies and damselflies both belong to the insect order Odonata, and both have aquatic immature stages. The most practical field difference is usually found at the end of the abdomen.
| Feature | Dragonfly nymph | Damselfly nymph |
|---|---|---|
| Typical body | Often broad, robust, oval or moderately elongated | Usually narrower and more slender |
| Tail structures | No three leaflike tail gills; usually several short pointed terminal appendages | Usually three elongated, leaflike caudal lamellae at the end of the abdomen |
| Main respiratory structures | Internal rectal gills | External caudal lamellae are important respiratory surfaces |
| Fast escape movement | Can expel water for jet propulsion | Often swims by moving the body and caudal lamellae |
| Wing pads | Visible in older nymphs | Also visible in older nymphs |
The British Dragonfly Society describes the caudal lamellae as finlike external gills that help distinguish damselfly larvae from dragonfly larvae.[2] However, damaged damselfly nymphs may temporarily lose one or more lamellae, so identification should use several features rather than the tail alone.
From Egg to Nymph: The First Stages of a Dragonfly’s Life
Female dragonflies place or release eggs in aquatic environments, but the exact method varies. Some species insert eggs into plant tissue, mud or decaying wood. Others release eggs directly into water or onto the water’s surface.
The brief prolarva stage
The first form that emerges from the egg is sometimes called a prolarva or pronymph. It is a short-lived, relatively inactive stage that may look more tadpole-like than later nymphs. When eggs hatch above the waterline, the prolarva may wriggle or drop into the water before molting. Eggs that hatch underwater can molt into the active first nymphal instar almost immediately.[2]
Repeated nymphal molts
The nymph cannot enlarge its rigid outer skeleton continuously. It must periodically shed that skeleton and form a larger one. Published general accounts give different molt totals because the number varies among species and because developmental stages may be counted differently. The British Dragonfly Society reports a further 5–14 molts after the prolarva, while the University of Florida gives 9–13 molts as a general range for dragonfly naiads.[2][3]
For that reason, claims that every baby dragonfly molts exactly six, ten or fifteen times should be treated as oversimplifications.
How Do Dragonfly Nymphs Catch Food?
Dragonfly nymphs are predators. Many remain motionless on plants, stones or sediment until prey comes close. Others slowly stalk through vegetation or crawl across the bottom.
Their diet can include mosquito larvae, midge larvae, mayfly nymphs, crustaceans, aquatic worms, small mollusks and other aquatic invertebrates. Large late-stage nymphs can also take tadpoles or small fish, although these larger prey should not be presented as the normal diet of every species.
The extendable “mask”
At rest, the labium folds beneath the head like a mask. During an attack, it unfolds and extends toward the prey. Earlier biomechanical research emphasized internal hydraulic pressure as an important driver of the strike.[4]
More recent experimental work has proposed a more complex mechanism: synchronized elastic structures act like a controllable dual-catapult system, storing and releasing energy to accelerate the mouthpart.[5] This research is a useful reminder that the familiar description of a purely “hydraulic jaw” does not capture the entire mechanism.
What laboratory research found
A 2018 study tested prey capture by emperor dragonfly (Anax imperator) larvae at different temperatures. Warmer conditions increased attack velocity, but capture success was not significantly reduced by the faster strikes. Success depended more strongly on whether the nymph aimed accurately.[6]
An earlier study involving five dragonfly species reported that larvae succeeded in roughly 60–70% of attacks on mosquito larvae, but only about 25–28% of attacks on amphipod crustaceans known as gammarids.[7] This demonstrates that prey type and behavior can influence hunting success. It does not support claims that every dragonfly nymph consumes a fixed number of mosquito larvae each day.
How Do Baby Dragonflies Breathe Underwater?
Dragonfly nymphs have internal respiratory surfaces in a chamber associated with the rectum. They draw water into this chamber and move it across the gills, allowing dissolved oxygen to enter the body.
This respiratory system is very different from the conspicuous external caudal lamellae of most damselfly nymphs. From the outside, a dragonfly nymph therefore appears to have no large external gills.
Jet propulsion
When a dragonfly nymph forcefully expels water from the rectal chamber, the water jet pushes the insect in the opposite direction. It can use this movement for rapid escape or repositioning.
A 2018 fluid-dynamics study found that dragonfly larvae can alter the symmetry of three anal valve leaflets, changing the direction and shape of water jets used during respiration and propulsion.[8] The system therefore acts as more than a simple open-and-close nozzle.
Where Do Dragonfly Nymphs Live?
Dragonfly nymphs occur in a wide variety of freshwater habitats. Different species may be associated with:
- Ponds, small lakes and reservoirs
- Marshes, swamps and seasonal wetlands
- Slow-moving streams and river margins
- Faster streams with gravel, sand or rocky bottoms
- Submerged vegetation, roots, leaf litter and woody debris
- Mud, sand or fine sediment used by burrowing species
Body form often reflects habitat. Long-bodied nymphs may climb among stems and submerged plants. Broad-bodied nymphs may rest on mud or leaf litter. Some clubtail nymphs are adapted to burrowing in sand or sediment.
How Long Do Dragonflies Stay in the Nymph Stage?
The answer depends on species, climate, water temperature, food supply, habitat stability and seasonal timing. There is no universal two-year or six-year rule.
The British Dragonfly Society states that larval development commonly lasts one or two years in the species it covers, but the broader range extends from months to more than five years. Cold water and limited food can slow development, while warm productive habitats may support faster growth.[2]
Important correction
Some general articles use the rapid two-to-three-month development of emerald damselflies as an example of dragonfly development. Emerald damselflies are damselflies, not true dragonflies. They belong to the same order, Odonata, but should not be presented as a dragonfly species.
Many dragonflies spend a much larger proportion of their total lives underwater as nymphs than they do flying as adults.
How Does a Dragonfly Nymph Become an Adult?
When development is complete, the final-stage nymph moves into shallow water and begins physiological changes that allow it to breathe air. It then climbs out of the water onto a plant stem, rock, bank, post or other secure surface.
It grips a stable support above the surface, sometimes during the night or early morning.
The thorax opens and the soft adult begins pulling itself out.
It pauses while its legs gain strength, then removes the abdomen from the old skin.
Body fluid is pumped into the wings, which unfold and increase to their adult size.
The newly emerged adult remains vulnerable until its wings and exoskeleton become firm enough for flight.
The empty skin left attached to the support is called an exuvia. It is not a dead dragonfly. Finding exuviae along a shoreline is evidence that dragonflies successfully completed their aquatic development at that location.
Why Are Dragonfly Nymphs Important?
Dragonfly nymphs occupy an important middle position in freshwater food webs. They are predators of smaller aquatic animals, but they are also eaten by fish, amphibians, water birds, larger insects and other dragonfly nymphs.
When adults emerge, nutrients accumulated during aquatic development are transferred from the water to surrounding terrestrial ecosystems. A 2024 literature review covering data for 109 odonate species reported that odonate larvae can be abundant components of freshwater communities, with a mean density of approximately 240 individuals per square meter across the studies included in the analysis. The authors also examined their role in moving biomass and nutrients from aquatic to terrestrial habitats.[9]
Are dragonfly nymphs indicators of clean water?
Odonates are widely used in ecological assessment because different species respond to water chemistry, vegetation, flow, sediment, shading, fish abundance and surrounding land use. However, the statement “a dragonfly nymph means the water is clean” is too simplistic.
A 51-pond Canadian investigation
Researchers compared 41 urban stormwater ponds with 10 natural reference ponds. They collected 774 dragonfly nymphs representing 22 species. Natural ponds averaged about 43 dragonfly nymphs, compared with about eight in stormwater ponds. Higher chloride and metal concentrations were associated with lower dragonfly abundance.
Yet water-quality variables explained less than one quarter of the overall variation in odonate community structure. The study concluded that habitat assessment should consider multiple environmental factors, not merely the presence or absence of one nymph.[10]
Scientists therefore obtain more useful information by examining which species are present, how abundant they are and how the entire aquatic community changes over time.
How to Find and Observe a Dragonfly Nymph Safely
Dragonfly nymphs can sometimes be observed among submerged plants, leaf litter, roots or shallow bottom sediment. They are easiest to see when material is examined carefully in a light-colored tray filled with water from the same habitat.
Avoid deep water, unstable banks, protected areas and places where collecting is prohibited.
Gently inspect submerged stems, leaves and roots rather than disturbing a large area of sediment.
Observe it in habitat water and minimize handling, heat exposure and time outside its original environment.
Useful identification photographs show the upper body, underside, wing pads and end of the abdomen.
Replace the nymph and disturbed habitat material gently unless a lawful scientific collection protocol applies.
Do not move dragonfly nymphs between ponds
Moving aquatic animals, plants, sediment or water can spread invasive organisms and pathogens. A nymph found during casual observation should be returned to the same place where it was collected.
Frequently Asked Questions
What is a baby dragonfly called?
A baby dragonfly is usually called a nymph or naiad. “Larva” is also widely used in field guides and general writing. Because dragonflies undergo incomplete metamorphosis and have no pupal stage, “nymph” is the more developmentally precise term.
Do baby dragonflies live in water?
Yes. Nearly all dragonfly nymphs are aquatic and develop in freshwater habitats such as ponds, wetlands, lakes and streams. The mature nymph leaves the water only when it is ready for its final molt into an adult.
Do baby dragonflies look like tadpoles?
Not during most of the nymphal stage. The very brief prolarva emerging from the egg may appear somewhat tadpole-like, but the active nymph soon develops the recognizable form of a six-legged aquatic insect.
How can I tell a dragonfly nymph from a damselfly nymph?
Damselfly nymphs are generally more slender and usually have three leaflike caudal lamellae at the end of the abdomen. Dragonfly nymphs are often broader and lack these three large external tail gills.
Do dragonfly nymphs eat mosquito larvae?
They can. Mosquito larvae may be part of the diet when the two occur in the same habitat and the prey is an appropriate size. Dragonfly nymphs are opportunistic predators, however, and also eat many other aquatic invertebrates. There is no reliable universal number of mosquito larvae eaten by every nymph per day.
Can a dragonfly nymph bite a person?
Dragonfly nymphs have functional mandibles and should be handled as little as possible. A large individual may pinch defensively, but it has no stinger and is not venomous. The greater concern is avoiding injury or stress to the nymph.
How long does a dragonfly live as a nymph?
Development can last from months to several years. Many temperate species require approximately one or two years, while some cold-water species may remain aquatic for more than five years. Temperature, food, species and habitat all affect the timing.
What is the empty shell beside a pond?
It may be a dragonfly exuvia—the empty outer skeleton left behind when a mature nymph climbed out of the water and emerged as an adult. Exuviae are often found attached to reeds, rocks, tree trunks, walls and bridge supports.
Does finding a dragonfly nymph prove that the water is clean?
No. Dragonfly species differ in pollution tolerance, and their distribution is also affected by vegetation, fish, temperature, sediment, water movement and surrounding land use. Community composition and abundance are more informative than the presence of one individual.
