Hydrotarsus pilosus is a special kind of beetle that belongs to the Dytiscidae family. These beetles are often called "diving beetles" because they are excellent swimmers. This particular species is found only in one place on Earth: the Canary Islands. This means it is endemic to these islands, making it very unique and important to protect.

What is Hydrotarsus pilosus?
Hydrotarsus pilosus is a small insect. Like all beetles, it has a hard outer shell that protects its body. It is part of a group known as diving beetles. These beetles are known for living in water. They have special adaptations that help them swim and breathe underwater.
Appearance and Size
Most diving beetles have a smooth, oval-shaped body. This shape helps them glide easily through the water. They usually have strong legs that are flattened and fringed with hairs. These legs work like paddles to push them through the water. While specific details about the size and exact color of Hydrotarsus pilosus are not widely known, most beetles in its family are small to medium-sized.
Diving Beetles: Masters of the Water
Diving beetles are fascinating creatures. They can stay underwater for a long time. They do this by carrying a bubble of air under their wing covers. This air bubble acts like a mini-scuba tank. When the beetle needs to refill its air supply, it swims to the surface. It pokes the tip of its abdomen out of the water to grab a fresh bubble.
Where Does Hydrotarsus pilosus Live?
This unique beetle lives only in the Canary Islands. These islands are located off the northwest coast of Africa. They are known for their beautiful and diverse natural environments. Being "endemic" means that this beetle species is native to and found exclusively in this specific area. You won't find Hydrotarsus pilosus naturally anywhere else in the world.
Habitat in the Canary Islands
Hydrotarsus pilosus likely lives in freshwater habitats on the islands. This could include ponds, slow-moving streams, or even temporary pools of water. These areas provide the perfect environment for diving beetles. They need water to hunt for food and to complete their life cycle. The specific conditions of these freshwater spots are crucial for the beetle's survival.
Life Cycle of a Beetle
Like all insects, Hydrotarsus pilosus goes through different stages in its life. This process is called metamorphosis. It helps the beetle grow from a tiny egg into an adult.
Reproduction and Early Life
The life cycle of a diving beetle typically starts with an egg. The female beetle lays her eggs in or near the water. Sometimes, she might lay them on aquatic plants. After a period, the eggs hatch into larvae.
Larval Stage
The larvae of diving beetles are often called "water tigers." They are fierce predators in their watery homes. They have strong jaws and hunt other small aquatic creatures. They grow by shedding their skin several times. This process is called molting.
Pupal Stage and Adulthood
Once the larva is fully grown, it leaves the water. It usually burrows into the soil or mud near the water's edge. Here, it changes into a pupa. This is a resting stage where the larva transforms into an adult beetle. After some time, the adult beetle emerges from the pupa. It then returns to the water to live, find a mate, and continue the life cycle.
Conservation Status
The taxobox shows that Hydrotarsus pilosus has a status of "EN." This means it is an Endangered species. This status is given by the International Union for Conservation of Nature (IUCN). Being endangered means that this beetle faces a very high risk of disappearing forever in the wild.
Why is it Endangered?
Species become endangered for many reasons. For Hydrotarsus pilosus, it's likely due to its limited habitat. Since it only lives in the Canary Islands, any changes to its freshwater homes can have a big impact. Threats might include:
- Habitat loss: When ponds or streams are drained or polluted.
- Climate change: Changes in rainfall patterns can affect water levels.
- Pollution: Chemicals from farms or towns can harm water quality.
- Invasive species: New species introduced to the islands might compete with or prey on the beetle.
Protecting the unique habitats in the Canary Islands is very important. This helps ensure that Hydrotarsus pilosus and other special species can survive and thrive for future generations.
