A total of 19 alien longhorn beetle species have established in Europe where they presently account for ca. 2.8 % of the total cerambycid fauna. Most species belong to the subfamilies Cerambycinae and Laminae which are prevalent in the native fauna as well. The alien species mainly established during the period 1975-1999, arriving predominantly from Asia. France, Spain and Italy are by far the most invaded countries. All species have been introduced accidentally. Wood-derived products such as wood- packaging material and palettes, plants for planting, and bonsais constitute invasive pathways of increasing importance. However, only few species have yet colonized natural habitats outside parks and gardens. Present ecological and economical impacts, and future trends are discussed.
