Neoclytus acuminatus

Neoclytus acuminatus, commonly known as the redheaded ash borer, is a species native to North America, including the United States and Canada. It is not native to Europe. This beetle is part of the Cerambycidae family and is known for its distinctive appearance and its larvae, which bore into dead or dying hardwood trees. Neoclytus acuminatus, or the red-headed ash borer, was first reported in Europe around 2008. It has been introduced accidentally, likely through the international trade of wood products. Since then, it has been observed in several European countries, where it has adapted to local environments and is considered an invasive species. Neoclytus acuminatus  is aroung 8–16 mm long beetle. The redheaded ash borer is a slender, agile beetle with long legs. Head and thorax brick-red colour, elytrae reddish-brown with 4 slim transversal yellow bands. Adults are easy to spot moving on timber stacks, but leave quickly if disturbed. They attack only declining or freshly dead/felled trees. Healthy trees, as well as dried wood, are neglected. Larvae feed initially under bark; later excavate tunnels in the wood. Adults emerge from circular holes, often in great numbers. It feeds on a wide spectrum of tree species in fruit orchards, parks, plantations, pure and mixed broadleaved forests.
