Calathus asturiensis facts for kids

Calathus asturiensis is a type of ground beetle. It belongs to the Platyninae subfamily. You can find this beetle in parts of France and Spain. It was first described in 1866 by a scientist named Vuillefroy.

What is a Ground Beetle?

Ground beetles are a large family of insects. They are known as Carabidae. There are over 40,000 different species worldwide. Most ground beetles are dark and shiny. They often have grooves on their wing covers. These beetles are usually found on the ground. They hide under rocks, logs, or leaves.

Where Do They Live?

Calathus asturiensis lives in France and Spain. Like many ground beetles, it prefers certain habitats. These can include forests, fields, and gardens. They often live in damp places. This helps them stay cool and find food.

What Do Ground Beetles Eat?

Most ground beetles are predators. This means they hunt other small creatures. They eat insects, slugs, and snails. Some ground beetles also eat seeds. They are helpful in gardens. They control pests naturally.

How Do They Hunt?

Ground beetles are active hunters. They often hunt at night. They have strong jaws. These jaws help them catch and eat their prey. They are fast runners. This helps them chase down their food.

Life Cycle of a Ground Beetle

Like many insects, ground beetles go through different life stages. This is called complete metamorphosis. It includes four main stages.

Egg Stage

The life cycle begins with an egg. Female beetles lay their eggs in the soil. They might also lay them under rocks. The eggs are usually small and white.

Larva Stage

After hatching, the egg becomes a larva. Larvae look like worms. They have strong legs and jaws. Larvae spend their time eating and growing. They shed their skin several times. This allows them to get bigger.

Pupa Stage

Once the larva is fully grown, it becomes a pupa. The pupa stage is a resting period. During this time, the larva changes into an adult beetle. This change happens inside a protective casing.

Adult Stage

Finally, the adult beetle emerges from the pupa. The adult beetle can then reproduce. It will lay eggs to start a new generation. Adult beetles live for several months. Some can even live for a few years.

Importance of Ground Beetles

Ground beetles play an important role in nature. They are part of the food chain. They help keep ecosystems healthy.

Natural Pest Control

Because they eat other insects, ground beetles are natural pest controllers. Farmers and gardeners like them. They help protect crops. They reduce the need for harmful chemicals.

Food Source

Ground beetles are also a food source. Many animals eat them. Birds, small mammals, and other insects prey on them. This makes them a vital part of the food web.
