Among fallen logs, stumps and piles of wood that smell of mature forest, lives one of the largest, most fascinating and robust insects in our fauna: the longhorn beetle. It is very strong, but equally slow. When disturbed, it can emit shrill sounds by rubbing the joints of its thorax. It is a saproxylic beetle, i.e. an insect that lives on decaying wood. Its larvae spend years inside dead beech, oak or chestnut trunks, digging tunnels: in this way, they help to decompose the wood and return useful nutrients to the soil. nbsp; Its presence indicates the good health of the forest: where it is found, dead wood still plays an important role in natural cycles! It reminds us that dead wood is not “forest rubbish”, but a treasure trove of biodiversity: it is home to fungi, larvae, mosses and a whole chain of organisms that keep the soil fertile and support the balance of the ecosystem.
