The family Cerambycidae, also known as the Longhorn beetles, is a very diverse group of beetles characterized by their long and slender bodies and particularly long antennae. The antennae are often as long or even longer than the body of the beetle itself. This family includes more than 35 000 species, which are found all over the world except Antarctica.
These beetles have very interesting life cycles and behaviours. Most adults feed on the nectar of flowering plants, but some species may also eat leaves, fruit or wood. The larvae of carpenter beetles develop inside wood, where they consume wood matter, promoting the decomposition of trees. This process can take several years before the larva reaches the pupal stage and eventually transforms into an adult.
Not surprisingly, a huge variety of colours and patterns can be found among carpenter beetles. Some individuals are relatively inconspicuous, while others have bold and contrasting colours that serve as a warning to predators. Some species even mimic the appearance of other dangerous or poisonous beetles, which protects them from predators.
Cerambycidae are found in a variety of environments, from tropical rainforests to temperate forests and savannas. Their presence is often an indicator of a healthy ecosystem, as their larvae play an important role in recycling nutrients and decomposing dead wood.
Although carpenter beetles are not a direct threat to humans, some species can cause damage to wooden structures or trees.
The study of these beetles provides valuable information about ecosystem functioning and conservation. In addition, their unique appearance and lifestyle attract the attention of both experts and the general public, making the Cerambycidae one of the most interesting groups of insects.
