What Do Dragonflies Use Their Tails For?

Dragonflies are flying insects belonging to the infraorder Anisoptera below the order Odonata, with about 3, 000 extant species known. They are fearsome hunters and carnivores, with their large, multifaceted eyes and strong, transparent wings providing them with a reproductive advantage. Some species use their wings as reflectors, tilting them to direct solar radiation towards their bodies.

Clubtail dragonflies, also known as blade tail dragonflies, belong to the Gomphidae family and have about 100 species. They are recognizable by their teeth and feet for hunting and can rip apart their prey. Dragonflies do not bite, but they do have ovipositing abilities, dropping small packages of eggs in the water.

Dragonflies don’t have diaphragms and lungs, but their “tracheae” pump their abdomen to promote gas exchange. They use various positional strategies to thermo-regulate, but dragonfly species like damselflies and hawker dragonflies have scythe-like ovipositors that inject their eggs into plant stems or leaves, rotten wood, or mud.

Dragonflies are used in traditional medicine in Japan and China, and caught for food in Indonesia. They are symbols of courage, strength, and happiness in Japan.

To control mosquitoes or other flying pests, dragonflies need agility, as they hunt other flying insects. They can move and rotate each of their four wings independently, and some point their wings forward and down to reduce exposure to sunlight and reflect light and heat away from their bodies.

How Do Dragonflies Eat?

Dragonflies are predominantly carnivorous insects, primarily feeding on other insects. An adult dragonfly perches with its abdomen held vertically to limit sun exposure and avoid overheating. These predators gather in groups in areas rich in insects, where they hunt collaboratively. Their diet mainly consists of mosquitoes, flies, moths, butterflies, and even other small dragonflies, as they are not selective eaters and will consume any available prey they can capture.

Dragonfly larvae, or nymphs, are also carnivorous and primarily consume aquatic insects, larvae, and even small fish and tadpoles. As adults, they are agile predators that capture prey mid-air using their long legs and powerful jaws, occasionally consuming their body weight in insects daily. They can catch and kill up to hundreds of mosquitoes in a single day.

Dragonflies possess exceptional vision that aids their hunting efficiency, making them one of nature’s skilled hunters. While they seek out flying insects, they are capable of eating a variety of available prey. Their primary feeding strategy involves catching insects on the wing, after which they transport their meal to a perch for consumption. This predatory behavior, combined with their speed and agility, makes them highly effective hunters throughout their life stages.

Why Do Dragonflies Dip Their Tails In Water?

Dragonflies exhibit a notable behavior known as "tail-dipping," where they dip their tails into water, primarily to lay eggs. This action is essential for their reproductive cycle, as female dragonflies insert their eggs into ponds or other standing water to prevent them from being washed away. While many assume dragonflies simply dip their tails in water for this reason, they sometimes engage in other behaviors related to hydration and hunting. Dragonflies can also drink water by thrusting their bodies onto the water's surface, allowing the exoskeleton to absorb moisture, and they can collect dew on cool mornings.

When observing a dragonfly repeatedly dipping its tail into water, it is usually indicative of egg-laying. Typically, dragonfly nymphs are aquatic, necessitating the eggs to be deposited in water. Some female dragonflies may also hover and flick water while laying eggs. Although it’s commonly thought that the eggs may be at risk in swimming pools due to chlorine, dragonflies choose locations that provide safety for their offspring.

Aside from reproduction, tail-dipping behavior may also be linked to courtship displays, primarily observed in male dragonflies. Overall, dragonflies are inherently drawn to water for breeding purposes, leading them to drop their eggs or attach them to nearby vegetation. This connection not only ensures successful reproduction but also highlights the remarkable adaptations of dragonflies.
