The Murray River hunter (scientific name: Austrogomphus angelorum) is a special type of dragonfly. It belongs to a group of dragonflies called Gomphidae, which are often known as "clubtail" dragonflies. This name comes from the way some of them have a wider, club-like end to their bodies.
This interesting insect is found in Australia. It lives in the slow-moving parts of the Murray River. You can find it in South Australia and along the border between New South Wales and Victoria. The Murray River hunter is a small to medium-sized dragonfly. It has a striking black and yellow pattern on its body.
Sadly, the Murray River hunter is listed as Vulnerable. This means its population is decreasing, and it needs our help to protect its home and future.

What is a Dragonfly?
Dragonflies are amazing insects known for their bright colors and incredible flying skills. They are part of an ancient group of insects called Odonata. Dragonflies have been around for millions of years! They are often confused with damselflies, but there are a few key differences.
Dragonflies usually hold their wings flat and out to the side when they are resting. Damselflies, on the other hand, often fold their wings back over their bodies. Dragonflies also tend to be larger and have thicker bodies than damselflies.
Where the Murray River Hunter Lives
The Murray River hunter dragonfly is a true Australian native. It makes its home in the Murray River, which is one of Australia's most important rivers. These dragonflies prefer parts of the river where the water flows slowly. This might include calm pools or quiet sections of the river.
Their habitat is very important for their survival. They need clean water and healthy riverbanks. These areas provide places for them to hunt, lay their eggs, and grow from young nymphs into adult dragonflies. Protecting the Murray River means protecting these unique creatures.
What the Murray River Hunter Looks Like
The Murray River hunter is a beautiful dragonfly with a distinct look. It is a small to medium-sized insect. Its body is a mix of black and bright yellow colors. This pattern helps it blend in with its surroundings or stand out to attract a mate.
Like all dragonflies, it has two pairs of strong, clear wings. These wings allow it to fly very fast and change direction quickly. It also has large, compound eyes. These eyes give it an almost 360-degree view of its surroundings. This is super helpful for spotting prey and avoiding predators.

The Life Cycle of a Dragonfly
Dragonflies like the Murray River hunter go through an interesting life cycle. It has three main stages: egg, nymph, and adult.
Egg Stage
The life of a Murray River hunter begins as a tiny egg. The female dragonfly lays her eggs in or near the water. She might place them on plants or directly into the water.
Nymph Stage
Once the egg hatches, a young dragonfly called a nymph emerges. Dragonfly nymphs live underwater. They are fierce predators, even at this stage! They eat small aquatic insects and even tiny fish. Nymphs breathe using gills, similar to fish. They grow by shedding their skin, a process called molting. This stage can last for several months or even a few years.
Adult Stage
When the nymph is ready, it crawls out of the water onto a plant stem or rock. Its skin then splits open, and the adult dragonfly emerges. This is a truly amazing transformation! The adult dragonfly's wings unfold and harden. Once ready, it takes its first flight. Adult dragonflies are also predators, catching insects like mosquitoes and flies in mid-air. Their main goal is to find a mate and start the cycle all over again.
Why is the Murray River Hunter Vulnerable?
The Murray River hunter is listed as Vulnerable by conservation groups. This means its population is at risk. There are several reasons why this might be happening:
- Habitat Loss: The places where they live, like the slow-flowing parts of the Murray River, can be damaged or disappear. This can happen due to changes in water flow, pollution, or human development.
- Water Quality: Dragonflies need clean water to survive. Pollution from farms or towns can harm both the adult dragonflies and their underwater nymphs.
- Climate Change: Changes in weather patterns, like droughts or floods, can also affect their habitat and food sources.
Protecting the Murray River and its environment is key to helping the Murray River hunter and many other species survive.
