Dragonflies are fascinating creatures known for their shimmering wings and brilliantly colored bodies. They can often be seen darting across the surface of lakes, streams, and wetlands, primarily feeding on smaller insects like mosquitoes and midges. This behavior might make some people wonder if dragonflies could also bite or harm humans.
The good news is that despite their fierce appearance and robust bodies, dragonflies do not sting or bite people. They are harmless to humans and can even be beneficial, as they function as natural predators for many small, pesky insects. Their agile, fast flight patterns make them excellent hunters in the skies, capturing their prey with their bristly legs.
In your garden, the presence of dragonflies can be an asset. They serve as living pest control, reducing the number of troublesome insects and providing an entertaining display of aerial acrobatics. So next time you spot a dragonfly, appreciate its beauty and its role as a helpful insect predator.
Dragonflies and Their Bites
Do Dragonflies Bite?
Yes, dragonflies can bite, but it’s important to note that their bites are neither harmful nor venomous. Larger species of dragonflies may deliver a pinching bite when handled, but they cannot harm people [^1^].
Is a Dragonfly Bite Dangerous?
A dragonfly bite is usually harmless to humans. As agile predators, they use their powerful jaws and mandibles to catch and consume flying insects such as flies, gnats, and mosquitoes. However, their bite poses no significant danger to humans.
The Dragonfly’s Jaws and Mandibles
Dragonflies have strong jaws and sharp mandibles, which they use for catching and consuming their prey. These features are well-adapted for their diet of flying insects, but they are not intended for attacking or harming humans.
Comparison of Dragonfly Bite impact:
| Insect | Bite | Effect on Human |
|---|---|---|
| Dragonfly | Pinching bite | Harmless |
| Mosquito | Piercing bite | Itchy, swelling |
| Bee | Piercing sting | Painful, swelling |
| Wasp | Piercing sting | Painful, swelling |
| Dragonfly Prey | Flying insects | Varies (depending on insect) |
| Dragonfly Bite | Humans | Harmless |
In conclusion, while dragonflies do possess the ability to bite, their bites are not harmful or dangerous to humans. Their jaws and mandibles serve as efficient tools for catching and consuming flying insects, but pose no significant threat to people.
Dragonfly Behavior and Characteristics
Life Cycle and Metamorphosis
Dragonflies have a fascinating life cycle that includes both aquatic and flying stages. Their first stage is the larval stage, where they live underwater as nymphs. These aquatic nymphs have gills and use jet propulsion to move through water. After undergoing metamorphosis, they emerge as adult dragonflies and take to the skies.
Some features of dragonfly nymphs include:
- Gills inside the rectum
- 6 legs
- Large eyes
- Eating small aquatic organisms
Adult Dragonflies and Their Hunting Abilities
Adult dragonflies are skilled predators that hunt flying insects, like mosquitoes and midges. They are known for their incredible agility, capable of flying in all directions and hovering in place. Dragonflies can reach speeds of up to 30 mph, making them some of the fastest insects in the world.
Some characteristics of adult dragonflies are:
- Large, powerful wings
- Exceptional eyesight
- Carnivorous diet
- Ability to catch prey mid-air
Common Nicknames and Misconceptions
Dragonflies are also known by various nicknames, such as “devil’s darning needle” and “horse-stinger.” However, these names perpetuate some common misconceptions about dragonflies.
Comparison table:
| Fact | Misconception |
|---|---|
| Dragonflies do not sting or bite humans | They are aggressive and will sting or bite humans |
| Adult dragonflies cannot break human skin | They can puncture human skin with their pointed spines |
| They lack venom | They are venomous insects like wasps and ants |
| Dragonflies majorly prey on mosquitoes | They mainly prey on larger insects like wasps and butterflies |
While dragonflies can nip in self-defense when threatened, they are not aggressive towards humans. Dragonfly bites are not venomous and are typically not painful or harmful to humans. Dragonflies are, in fact, beneficial insects that play a role in controlling mosquito and other small flying insect populations.

Good morning,
If I may add a correction, this is a Comet darner (Anax longipes), a rather young male, with the orange abdomen, green thorax and forhead without the round spot, called bull’s eye, that the Green darner have.
I hope this helps,

Thank You so much Daniel, I never would have guessed that the difference was just a matter of age. I have learned more from you and your website then any place in a long time. (Just proves that you are never too old to learn.)
It’s a Common Tigertail!
Hello,
That larvae is of the Clubtails (Gomphidae) family which larvae often have funny looking shape. Thick antennae are a clue to that family. Some like yours have elongated back end, sometimes as long as the rest of the body, they use to breath while burried into sediment stalking for preys.

Hello,
It is of some Clubtails species. Larvae of that family of many genus has often funny looks. Its elongated end works as siphon to breath while burried in sediments.

Two-striped Forceptail – Aphylla williamsoni
Thanks. We will update the posting and attempt to find some links to illustrate the identification.
