aromia

Aromia is a genus of beetles in the family Cerambycidae, commonly known as longhorn beetles. The genus comprises two described species: Aromia moschata, the musk beetle, and Aromia bungii, the red-necked longhorn beetle. Aromia moschata is native to Europe and western Asia, while Aromia bungii is native to East Asia. Invasive occurrences of A. bungii have been reported outside its native range, prompting monitoring and quarantine measures in some regions.

Aromia moschata, the musk beetle, is typically 12–25 mm long and has a metallic green body with reddish legs. Adults are often found near deciduous trees along rivers and in woodlands, particularly where willows (Salix) and poplars (Populus) grow. The larvae are wood-borers that develop under the bark and into the sapwood of living or recently dead trees. The species usually completes its life cycle over one to two years, depending on climate.

Aromia bungii, the red-necked longhorn beetle, is about 16–28 mm in length. It is characterized by a red prothorax (the “neck”) and darker elytra. Native to East Asia, it has become a pest in areas where it has been introduced, as its larvae bore into the trunks and branches of a wide range of hardwood trees, including fruiting and ornamental species. Lifecycles are also variable by climate, with larval development spanning several months to years before adults emerge.

Ecology and management emphasize monitoring host trees, restricting movement of infested wood, and implementing quarantine where A. bungii has established. Both species are of interest to forestry and entomology due to their wood-boring lifestyles and potential impact on host trees.
