Neoclytus acuminatus (Fabricius, 1775) - (red-headed ash borer)
This small long-horned beetle is native to North America, and has been accidentally introduced into Europe and other regions. It normally breeds in the trunks of felled trees, but can also attack young and stressed mature trees. The hosts are most often ash and oak trees but can include various other deciduous tree species.
N. acuminatus is of quarantine concern in many countries, as it can be transported inside sawn timber. The native range includes the central and eastern parts of North America. The invaded regions are western North America, part of the Caribbean, Argentina and Europe. There have been several introductions into Europe since around 1850, and it is now established in the Madeira Islands, Germany, Italy, as well as in south-eastern Europe including Austria, Hungary and the Balkan region (Keszthelyi, 2021).

The adult beetle is between 10 and 15 mm long and reddish brown, interrupted by 4 yellow transverse bands. The life cycle is usually one year, with the adults emerging from the logs in spring. The larvae develop over the summer and autumn and overwinter in the wood.
