Mô tả sản phẩm

The English name for "kẽm nhung" is velvet ant. These fascinating insects are actually a type of wasp, known for their striking appearance and painful sting.

Identifying Velvet Ants

Physical Characteristics

Velvet ants are characterized by their dense, velvety hair, often in vibrant colors like red, orange, black, or a combination thereof. They are typically wingless females, although males possess wings and a different appearance. Their size varies depending on the species, but they are generally small to medium-sized.

Habitat and Distribution

Velvet ants are found worldwide, inhabiting diverse environments, including sandy areas, grasslands, and open woodlands. They are often found in nests in the ground, utilizing abandoned rodent burrows or similar spaces.

The Infamous Sting

Pain Level and Medical Considerations

Velvet ants are renowned for their excruciating sting, often ranked among the most painful insect stings. The pain is described as intense, burning, and long-lasting. While generally not life-threatening to healthy adults, allergic reactions are possible, requiring immediate medical attention. For those with known allergies, carrying an epinephrine auto-injector is crucial.

Defense Mechanisms

The intense sting serves as a primary defense mechanism against predators. Their bright coloration often acts as a warning signal, a phenomenon known as aposematism, alerting potential predators to their potent sting.

Ecological Role

Parasitoid Behavior

Many velvet ant species are parasitoids, meaning their larvae develop inside the nests of other insects, often consuming their host. This plays a crucial role in regulating populations of their host insects within their respective ecosystems.

Importance in Biodiversity

Despite their painful sting, velvet ants contribute to the overall health and balance of ecosystems. Their role as parasitoids helps maintain biodiversity by controlling populations of other insects.
