Its massive mandibles, resembling the horns of a bull, have given it the nickname “timber tiger.” These beetles have a peculiar biology, with their larvae spending up to three years feeding on decaying wood before emerging as adults. The Prionus horned beetle is an important decomposer, contributing to the recycling of nutrients in forest ecosystems.

Biology and Lifecycle of Longhorn Beetles: A Fascinating Journey

From Egg to Larva:

The life of a longhorn beetle begins as a tiny egg, carefully placed by the female in the crevices of tree bark or wood. As the egg hatches, a small, worm-like larva emerges, ready to embark on its journey of growth and development.

Larval Stage: The Hidden Life

Larvae of longhorn beetles spend most of their lives concealed within the wood of their host plants. They feed voraciously on the wood, creating intricate tunnels and chambers as they grow. Some species can remain in the larval stage for several years, patiently feeding and developing.

The Dramatic Transformation to Adult:

When the larva reaches maturity, it constructs a pupal chamber within the wood. Inside this chamber, the larva undergoes a remarkable metamorphosis, transforming from its worm-like form into a beautiful, long-horned adult beetle.
