Dragonfly vs Damselfly
Verdict: Check the wings at rest and the eyes. Dragonflies hold their wings out flat and have big eyes that touch or nearly touch. Damselflies fold their wings along the body and have eyes set wide apart.
Dragonflies and damselflies are both Odonata, the order of insects with long bodies, four wings and aquatic young. They share ponds and streams, and the quickest sorting trick is to look at a perched insect. A dragonfly sits with its wings spread like a small airplane. Most damselflies fold theirs back over the body.
The head and body also differ. Dragonflies have big eyes that dominate the head, and a thick, sturdy body. Damselflies have smaller eyes with a visible gap between them and a slim, twig-like abdomen. One exception is the spreadwing damselfly family, which holds the wings partly open, so check the eyes too.
Dragonfly vs Damselfly side by side
| Trait | Dragonfly | Damselfly |
|---|---|---|
| Wings at rest | Held out to the sides, like an airplane | Folded together along the body (spreadwings hold them partly open) |
| Eyes | Large, touching or nearly touching, dominating the head | Smaller, separated by a gap about an eye width or more |
| Body | Thick, robust, chunky | Very slim, twig-like |
| Typical length | Often over 2 in | About 1.5 in |
| Wing shape | Hind wings broader than forewings | Fore and hind wings similar and narrow near the base |
| Flight | Strong, agile and deliberate | Weaker, fluttering |
| Habitat | Ponds, open water and fields | Pools, shorelines and grasses near water |
| Young (naiads) | Aquatic predators of insects, tadpoles and small fish | Aquatic predators of insects, tadpoles and small fish |

When you are looking at which
Dragonfly
- A perched insect with its wings flat out to the sides like an airplane.
- A big head that looks mostly eyes, with the eyes meeting on top.
- A stocky, strong-flying insect patrolling a pond or even a field.
- A body longer than 2 inches with a thick abdomen.
Damselfly
- A delicate insect resting with the wings pressed together along its back.
- A head with eyes clearly set apart on either side.
- A very thin, twig-like body, often bright blue, red or green, perched on a stem near water.
- A weak, fluttery flight low over vegetation at the water's edge.
How this works
The quiz asks about wing position, eye spacing, body build, size and flight, then tallies the cues for each. If you skip a cue the result still works, since any two agreeing cues are strong. Eye spacing counts the most, because it holds even when a damselfly holds its wings partly open, as spreadwings do.
Spreadwing damselflies and some small dragonflies break the usual size and wing rules. Eye spacing and body shape are the steadiest cues. A regional field guide can identify species. If you want the species, note the size, color, and where you saw it, then check a regional dragonfly guide.
Where these numbers come from
The figures and defaults on this page are based on:
- University of Florida IFAS: Dragonflies and Damselflies (EENY355), Wings at rest, eye spacing, body build, flight and nymph diet (checked October 2026)
- University of Illinois Extension: Dragonflies and Damselflies, Wing posture, eye size and typical lengths (checked October 2026)
- Scottish Wildlife Trust: Dragonflies and Damselflies, Wing posture, eyes, body and wing shape (checked October 2026)

Frequently asked questions
Why are they always near water?
Their young, called naiads, live in the water as predators of small animals such as mosquito larvae. Adults stay close: dragonflies over ponds and open water, damselflies along shorelines and in grasses.
What is the easiest way to tell them apart?
Look at a perched insect. A dragonfly rests with the wings out flat, while most damselflies fold them back over the abdomen, and the eyes also differ.
Are there damselflies that hold their wings open?
Yes. The spreadwing family, Lestidae, rests with its wings partly open. Check the eyes and body, which will still look damselfly-like.
What do the young eat?
Both live in water as nymphs, also called naiads, and eat insects such as mosquito larvae and sometimes small vertebrates such as tadpoles and small fish.
