What Do Dragonfly Eggs Look Like?
Dragonfly eggs are tiny, usually well under 1 millimeter, and most people never notice them. Their appearance depends mainly on how the female lays them. Eggs dropped onto water are small, round to oval, and often wrapped in clear, sticky jelly. Eggs pushed into plant stems are longer and narrower, roughly like a grain of rice, and are hidden inside the plant. Many freshly laid eggs start out whitish, cream or pale yellow and turn brown after they reach water.
That is the short answer. The details below explain why eggs differ so much between groups of dragonflies, what you might realistically see at a pond, and how to avoid mistaking other pond eggs for dragonfly eggs.
Two Basic Kinds of Dragonfly Eggs
Specialists usually describe two main egg-laying styles, and each comes with a different egg shape. (A third, less common style places eggs on the surface of plants rather than inside them.)
| Eggs laid on or into water (exophytic) | Eggs inserted into plants or other material (endophytic) | |
|---|---|---|
| Shape | Round, oval or slightly elongated | Long and narrow, like a grain of rice or a spindle |
| Coating | Often a clear, sticky jelly that swells in water | Usually none needed; the plant tissue protects them |
| Where they end up | Sink to the bottom or stick to plants, stones and debris | Inside stems, leaves, soft or rotting wood, mud or similar material |
| Typical true dragonfly groups | Skimmers, chasers and darters (Libellulidae), emeralds and baskettails (Corduliidae), clubtails (Gomphidae) | Darners/hawkers (Aeshnidae) and petaltails (Petaluridae) |
| What you usually see | Specks in jelly, jelly clumps or jelly strings | Not the eggs themselves, but small slits or scars where the female cut into the plant |
A UF/IFAS Extension publication on Odonata describes eggs laid inside plant tissue as several times longer than they are wide, while eggs laid on plant surfaces, water or land are ellipsoidal to nearly spherical.
Damselflies are a separate suborder (Zygoptera), but they matter here because all damselflies insert their eggs into plants or other material. So an elongated egg hidden in a stem may belong to a damselfly rather than a true dragonfly.
How Big Are Dragonfly Eggs?
Odonata eggs are generally somewhere around 0.5 to 1.5 millimeters, according to the Bedfordshire Odonata recording site. Most are smaller than a pinhead.
Measured examples show how much they vary:
- In a study of Sympetrum danae (black darter) in Austria, newly laid eggs measured about 0.53 × 0.38 mm (Waringer 1983).
- In a 2022 study of libellulid dragonflies in India, egg length ranged from about 0.29 mm in Neurothemis tullia, a very small, nearly round egg, to about 0.62 mm in the longer, cylindrical egg of Brachythemis contaminata (Verma 2022).
These numbers apply to the species measured. They are useful for a sense of scale, not as a fixed size for every dragonfly egg. Endophytic eggs are longer than they are wide by design, so a single “egg size” does not describe both groups well.
What Color Are Dragonfly Eggs?
Many dragonfly eggs are pale when they leave the female and darken soon afterward. The timing differs by species:
- Sympetrum danae: newly laid eggs were whitish, and the outer shell turned dark brown within about 18 hours (Waringer 1983).
- Neurothemis tullia: the eggs changed from cream to brown within about 20 minutes in water (Verma 2022).
- Acisoma panorpoides: the eggs were yellow when released and turned brown within an hour (Verma 2022).
- Pantala flavescens (wandering glider): freshly laid, still-dry eggs were described as pale yellow and slightly sticky (Verma 2022).
So “pale at first, brown later” is a common pattern in the species that have been studied, but not a rule you can apply to every species. Eggs carried by a female before release can also look different. Baskettail females in North America, for example, carry their eggs as a small orangish mass at the tip of the abdomen before dropping them, as described by the Missouri Department of Conservation.
The Jelly Coating
Many eggs laid on water have a thin outer layer that swells once it gets wet. In the 2022 Indian study, this layer expanded in water into a thick, transparent, sticky jelly that anchored the eggs and helped them stick to the bottom or to plants. In Pantala flavescens, the sticky coatings of neighboring eggs fused together into an egg mass.
The jelly does not always stay sticky. In Sympetrum danae, each egg sat in a jelly layer about 0.22 mm thick. It was sticky at first, holding egg batches together and attaching them to surfaces, but after a few hours it became firmer and more elastic and lost its stickiness (Waringer 1983).
Clubtails offer another example. The University of Wisconsin–Milwaukee Field Station notes that clubtail eggs are often held in a gelatinous coating that sticks to plants or rocks, which helps keep them from washing away in flowing water.
To the naked eye, a jelly-coated batch looks like a small, clear or cloudy blob with tiny pale or brown dots inside.
Egg Strings: Baskettails
The most noticeable dragonfly eggs belong to the baskettails (Epitheca), a group of emerald dragonflies found in North America.
Instead of scattering eggs one by one, a baskettail female releases a clump that swells and uncoils in water into a rope-like strand of jelly, often draped over submerged plants. For the prince baskettail (Epitheca princeps), the University of Wisconsin–Milwaukee Field Station describes strands of up to about 20 inches long holding as many as 1,000 eggs. The Missouri Department of Conservation says baskettail egg strands can reach a few feet in length.
If you find a long, gelatinous string tangled in pond plants in a region where baskettails occur, it could be a baskettail egg strand. It could also be something else, such as toad spawn, so read the comparison section below before deciding.
Eggs Hidden Inside Plants
Darners, hawkers and petaltails, along with all damselflies, use a blade-like ovipositor under the tip of the abdomen to cut into a surface and place each egg inside.
The Shropshire Dragonflies recording site notes that these eggs usually go into plant tissue but can also be placed in other material. It gives the brown hawker (Aeshna grandis) as an example of a species that lays in wood, rotten wood or mud. Some species lay above the waterline. The migrant hawker (Aeshna mixta), for instance, uses vegetation above the water.
Because the eggs are inside the material, you normally cannot see them at all. What you may notice instead are tiny slits or scars in stems, floating leaves or soft wood. Some species place their eggs in a characteristic pattern, so a careful observer may see small, regular rows of marks.
Damselflies can go further. The same Shropshire source notes that the common blue damselfly (Enallagma cyathigerum), a damselfly rather than a true dragonfly, can climb down a plant stem as deep as about 1 meter underwater to lay eggs. Read more in our common blue damselfly profile.
How Many Eggs Does a Dragonfly Lay?
Egg numbers vary widely by species and by individual. The UF/IFAS Extension publication reports clutches of up to about 1,500 eggs, and notes that some females lay several thousand eggs over their lifetime. The baskettail strand mentioned above may contain about 1,000 eggs.
Laying speed differs too. Females that insert eggs one at a time into plants work slowly. Females that release eggs onto the water can lay them very quickly. The Shropshire Dragonflies site cites rates of 1 to 18 eggs per minute for endophytic laying and more than 1,000 per minute for some exophytic laying, without tying either figure to a particular species.

What Changes Inside the Egg Before It Hatches
From the outside, a dragonfly egg does not change much once it has darkened. Inside, the embryo develops over days, weeks or months.
The Austrian study of Sympetrum danae traced this in detail. Under magnification, the embryo was fully segmented, with eyes, legs, antennae and mouthparts, around two weeks after laying. These eggs then waited through winter. Full development took about 217 to 239 days at a mean water temperature of 10.8°C (about 51°F), and half of the larvae hatched within the first three days of a 22-day hatching period (Waringer 1983).
Many other species hatch much sooner. The UF/IFAS publication gives about a week as typical, with delays of up to 80 days and one recorded case of 360 days. Temperature, species and season all affect the timing, which is why no single hatching time applies to all dragonflies.
When the egg hatches, the young does not look like a dragonfly. It emerges as a brief prolarva and then molts into an aquatic nymph. Our guide to what baby dragonflies look like covers that next stage, and the dragonfly life cycle hub explains the full sequence from egg to aquatic nymph to adult. There is no pupa or chrysalis stage.
How to Tell Dragonfly Eggs From Other Eggs in a Pond
Ponds are full of eggs, and several kinds can be confused with dragonfly eggs:
- Frog and toad spawn. These eggs are much larger than dragonfly eggs, and each one has an obvious dark center. Frogs often lay clumps, while toads often lay long strings, which could be mistaken for a baskettail strand at a glance.
- Snail eggs. Many freshwater snails lay their eggs in clear jelly patches or bands stuck to leaves, stems, stones and pond walls. These are among the most common jelly masses in garden ponds and can look a lot like a dragonfly egg mass.
- Other aquatic insects. Several other insects that breed in water also lay eggs in jelly.
The most reliable clue is behavior. If you watched a female dragonfly tap her abdomen on the water or cut into a stem, and then found eggs or fresh slits in that exact spot, you have good evidence. A jelly blob found later, with no laying observed, is much harder to confirm.
Even when you are sure the eggs came from a dragonfly, you usually cannot tell the species from the eggs alone. To identify the parent, focus on the adult and its location, date, habitat and markings, as explained in our dragonfly identification guide.
Tips for Seeing Dragonfly Eggs Yourself
- Watch egg-laying females. Look for a female dipping the tip of her abdomen into the water, or perched on a stem or log with the abdomen curled down against it.
- Use a hand lens. Eggs are too small to see clearly without magnification. A hand lens or a phone camera’s macro mode helps.
- Look but don’t collect. Avoid pulling up plants, scraping jelly masses or cutting into stems to find hidden eggs. Leave egg-laying vegetation in place.
- Don’t move eggs between ponds. Moving eggs, plants or water from one site to another can spread unwanted species and disease.
- Check calm, plant-rich edges. Many dragonflies breed where there is open water with plants at the margins. See do dragonflies live near ponds? for more.
Frequently Asked Questions
Can you see dragonfly eggs with the naked eye?
Usually only as tiny specks. Single eggs are mostly well under a millimeter long. A jelly mass or a baskettail egg strand is easier to spot, but you need a hand lens to see individual eggs clearly.
Do dragonfly eggs float?
Most eggs laid onto water do not float for long. The Shropshire Dragonflies site describes them as washing off the female’s abdomen and sinking, and many have a sticky coating that attaches them to plants, stones or debris.
Are dragonfly eggs the same as damselfly eggs?
Not exactly. All damselflies insert their elongated eggs into plants or other material. True dragonflies are split: darners/hawkers and petaltails also insert eggs, while skimmers, emeralds, clubtails and several other groups lay rounder eggs onto water.
How long do dragonfly eggs take to hatch?
It depends on the species and temperature. Some hatch in about a week, others in several weeks, and some species wait through winter and hatch the following spring.
Do dragonfly eggs hatch into tiny dragonflies?
No. They hatch into a short-lived prolarva that quickly molts into an aquatic nymph, also called a larva. The nymph lives underwater, often for months or longer, before it emerges as a winged adult. Visit our dragonfly larvae hub to learn more.
