Trechus is a large group, or genus, of small ground beetles. These beetles are found in many places around the world. You can find them across Europe, the Middle East, and northern Asia. There are hundreds of different kinds, or species, of Trechus beetles.
The name Trechus comes from an old Greek word, trécho. This word means "I run," which is a good name for these quick little beetles!
Scientists first put these beetles into their own group, or genus, in 1806. This was done by a scientist named Joseph Philippe de Clairville.

What Are Ground Beetles?
Ground beetles are a big family of insects. They are known for living on the ground, as their name suggests. Most ground beetles are active at night. They often hide under rocks, logs, or leaves during the day.
These beetles have strong legs for running fast. They also have hard wing covers that protect their bodies. Many ground beetles are dark in color, like black or brown. This helps them blend in with their surroundings.
Where Trechus Beetles Live
Trechus beetles live in many different habitats. They can be found in forests, grasslands, and even mountains. Some species prefer damp places, like near rivers or streams. Others live in drier areas.
These beetles are often found under stones or in leaf litter. They like places where they can hide easily. Their small size helps them fit into tiny cracks and spaces.
The Life Cycle of a Trechus Beetle
Like all beetles, Trechus beetles go through a complete metamorphosis. This means they change a lot during their lives. Their life cycle has four main stages: egg, larva, pupa, and adult.
From Egg to Larva
A female Trechus beetle lays tiny eggs. She usually lays them in the soil or under debris. After a short time, a small larva hatches from each egg. The larva looks like a tiny worm.
The larva's main job is to eat and grow. It sheds its skin several times as it gets bigger. This process is called molting. Each time it molts, it enters a new larval stage.
The Pupa Stage
Once the larva is fully grown, it changes into a pupa. The pupa stage is like a resting period. During this time, the beetle transforms inside a protective casing. It does not eat or move much.
Inside the pupa, the larva's body changes into the adult form. This is a bit like a caterpillar changing into a butterfly inside a chrysalis.
Becoming an Adult Beetle
Finally, the adult Trechus beetle emerges from the pupa. The adult beetle has its hard wing covers and fully formed legs. Its main jobs are to find food and to reproduce.
Adult Trechus beetles can live for several months. They are an important part of their ecosystem.
What Trechus Beetles Eat
Most Trechus beetles are predators. This means they hunt and eat other small creatures. They mainly feed on tiny insects and other small invertebrates. These can include springtails, mites, and small worms.
They use their strong jaws to catch and eat their prey. By eating these small creatures, Trechus beetles help to control insect populations in their habitats.
Interesting Facts About Trechus
- Many Trechus species are quite small, often less than half an inch long.
- Some Trechus beetles live in caves. These cave-dwelling species often lose their eyesight because they live in total darkness.
- Scientists are still discovering new species of Trechus beetles. This shows how much there is still to learn about the natural world!
