Adrastus
Eschscholtz, 1829
|
Adrastus is a genus (a group of related species) of beetles. These fascinating insects belong to a family called Elateridae, which are commonly known as "click beetles." They get their name from a special trick they have!
Scientists first grouped these beetles into the Adrastus genus in 1829. This was done by a famous scientist named Johann Friedrich von Eschscholtz.

What Makes Adrastus Click Beetles Special?
Click beetles, including those in the Adrastus genus, are famous for their unique ability to "click." If a click beetle lands on its back, it can snap a part of its body to flip itself over. This makes a loud clicking sound.
The Amazing Click!
How do they do it? Click beetles have a special hinge between their first two body segments. When they are on their back, they can bend this hinge. Then, they quickly release it, causing their body to snap. This action launches them into the air.
The click helps them escape from predators. It also helps them get back on their feet. It's a very clever way to survive in the wild.
Where Do Adrastus Beetles Live?
Adrastus beetles can be found in various parts of the world. They often live in grassy areas, fields, and forests. You might spot them on plants or under rocks and logs.
They prefer places where they can find plenty of food. They also need good spots to lay their eggs. Their habitat is important for their survival.
What Do Adrastus Beetles Eat?
Like many beetles, Adrastus species have different diets. Adult click beetles often feed on plant nectar or pollen. Some might even eat small insects.
Their larvae, which are young beetles, are called wireworms. Wireworms live in the soil. They usually feed on plant roots. Sometimes, they can be a pest to crops.
The Life Story of a Click Beetle
Click beetles go through a complete metamorphosis. This means they have four main life stages. These stages are egg, larva, pupa, and adult.
- Eggs: Female beetles lay tiny eggs in the soil.
- Larvae: The eggs hatch into long, hard-bodied larvae called wireworms. They live underground for a long time, sometimes several years.
- Pupae: After growing, the wireworms turn into pupae in the soil. This is a resting stage where they transform.
- Adults: Finally, the pupae change into adult click beetles. The adults emerge from the soil to mate and lay new eggs.
