Dragonflies are an ancient group of insects that have been around for 300 million years, dating back to the time of the dinosaurs. With their superb flying skills and excellent vision, they are perfectly designed to hunt smaller insects. Dragonflies are common around Australia wherever there is freshwater, such as a pond, stream, river or lake. But what exactly do they eat?

What You'll Learn
Dragonfly larvae eat mosquito larvae
Dragonflies are large, conspicuous insects with more than 320 species known to live in Australia. They are common around the country, especially in Queensland, wherever there is freshwater such as a pond, stream, river or lake. Dragonflies are excellent hunters of other flying insects and can hover, move in zigzags, and even fly backwards. They are also very fast, with some larger dragonflies reaching flying speeds of 70 km per hour.
Dragonfly larvae are aquatic or semi-aquatic and are known as mud-eyes. They are predatory and must survive in water for a long time, sometimes years. They spend time in the benthic layer and cannot breathe air directly. Instead, they have to absorb oxygen from the water, diffused like gills do. Dragonfly larvae are found in moving water environments that contain more oxygen.
Mosquito larvae, on the other hand, are found in small bodies of still or stagnant water that likely have a low oxygen content. They float near the top and stick their breathing tube to the water surface, where they sit and develop.

Adult dragonflies eat mosquitoes
Dragonflies are an ancient and successful group of insects that have been around for around 300 million years. They are found near freshwater habitats, such as ponds, streams, rivers, and lakes, and are common throughout Australia, especially in Queensland. With their superb flying skills and excellent vision, dragonflies are perfectly designed to hunt smaller insects such as mosquitoes.
Dragonflies are mosquito-eating predators. Adult dragonflies eat mosquitoes, as do their larvae, or babies. In fact, dragonfly larvae feed on mosquito larvae, helping to keep mosquito numbers down. According to Nature Glenelg Trust ecologist Bryan Haywood, a population of dragonflies at a wetland can consume hundreds of thousands of mosquitoes. He estimates that 100 dragonflies can eat 100 mosquitoes in an hour, amounting to millions of mosquitoes every day.
Adult dragonflies are often found close to water, where they hunt flying insects. Their legs point forward, forming a basket to capture prey in mid-flight. They are also capable of hovering, moving in zigzags, and even flying backward. Some of the larger dragonflies can reach flying speeds of 70 km/h, possibly making them the fastest flying insects on Earth.
Dragonflies are beneficial to have around, as they help control mosquito populations. They are harmless to humans, despite their powerful jaws, and are an important indicator of water quality.

Dragonflies eat other flying insects
Dragonflies are ancient insects that have been around for around 300 million years. They are known for their powerful flying abilities and well-developed eyes. With their superb flying skills and excellent vision, dragonflies are adept hunters of other flying insects. They can hover, move in zigzags, and even fly backwards. They are also incredibly fast, with larger dragonflies reaching flying speeds of up to 70 km/h, making them possibly the fastest flying insects on Earth.
Dragonflies are found near freshwater habitats, such as ponds, streams, rivers, and lakes. They are common throughout Australia, especially in Queensland. These insects are excellent hunters and play an important role in controlling mosquito populations. Both adult dragonflies and their larvae, known as nymphs, feed on mosquitoes. Adult dragonflies also eat White Cabbage butterflies and other flying insects, which they grab in mid-air.
Dragonflies have a distinctive appearance, with a wide body and two pairs of wings that lie flat when they are at rest, just like when they are in flight. They can be up to 15 centimetres in length, with a wingspan of up to 70 centimetres in ancient times. Today, their wingspan ranges from 40 mm for the Eastern pygmyfly to 10 cm for the Australian emperor.
Dragonflies are an important part of wetland ecosystems and are considered bioindicators of water quality. They are dependent on healthy waterways and require permanent or semi-permanent water bodies for breeding and egg-laying. Dragonflies are fascinating creatures that play a crucial role in maintaining the balance of their ecosystems, especially in controlling mosquito populations.

Dragonfly nymphs eat small fish
Dragonflies are large, conspicuous insects generally found near freshwater habitats. They are excellent hunters of other flying insects and can hover, move in zigzags, and even fly backwards. They are also extremely fast, with some larger dragonflies reaching flying speeds of 70 km per hour.
Dragonfly nymphs are the larval stage of dragonflies. They are well-armoured, patient, tough, and quick, with strong grasping forelimbs. They are also very capable predators. Dragonfly nymphs can eat a lot and will eat anything they can catch, including small fish. They are often found in ponds, lakes, and rivers, where they can feed on small fish and other prey.
Dragonfly nymphs are born hunting machines and are very fast and efficient hunters. They use their camouflage and slow movement to be as inconspicuous as possible when hunting. They can also sit motionless for days, making them very good at hiding from predators.
Dragonfly nymphs are a problem for shrimp tanks, as they will eat the shrimp. Some people have suggested using fish, such as mollies, to eat the dragonfly nymphs. However, this is not a guarantee, as the nymphs are very good at hiding and can sit motionless for long periods.
Dragonfly nymphs can also be used as bait for trout fly fishing. Nymphs are found in most western lakes, ponds, and still waters of rivers, where they provide a large meal for trout. Fly fishers need to understand the life and mannerisms of dragonfly nymphs to be successful in catching trout.

Dragonfly nymphs eat tadpoles
Dragonflies are ancient insects, dating back to before the dinosaurs. There are over 300 species of dragonflies in Australia, and they are found near freshwater habitats such as ponds, streams, rivers, and lakes. Dragonflies are excellent hunters, feeding on mosquitoes, midges, and other flying insects.
Dragonfly nymphs, or larvae, are also predatory and feed on a variety of aquatic animals. They are well-adapted hunters, with strong forelimbs and a highly modified lower lip, or labium, which they use to catch their prey. Dragonfly nymphs are known to eat shrimp, snails, small fish, tadpoles, and even other dragonfly nymphs.
Dragonfly nymphs are voracious eaters and will consume anything they can catch that is their size or smaller. They are patient and tough, with strong grasping forelimbs that allow them to capture their prey. In addition to tadpoles, dragonfly nymphs have been observed to eat small fish, frogs, and even baby turtles.
Tadpoles, therefore, form an important part of the diet of dragonfly nymphs. They are well-equipped to catch tadpoles and other small aquatic creatures, and their presence in a pond or tank can have a significant impact on the population of these creatures. Dragonfly nymphs are known to be efficient hunters and can eat a lot, making them a force to be reckoned with in aquatic ecosystems.
Overall, dragonfly nymphs are fierce predators that play a crucial role in the food chain of freshwater ecosystems. Their diet includes tadpoles, among other small aquatic organisms, and they are well-adapted to hunting and consuming a variety of prey.
