Jewel beetle Coraebus rubi

Coraebus rubi, a jewel beetle from the family Buprestidae, is a cane-boring species whose larvae develop inside the stems of shrubs and canes. Adults feed on the foliage of Rubus and Rosa. The species typically has a two-year lifecycle. While the intensity of infestation is usually not high, repeated damage can gradually weaken the host plant. It occurs in central and southern parts of Europe. Its spread is often linked to the movement of infested plant material. From an aesthetic standpoint, boring damage may reduce the visual value of ornamental or wild-growing shrubs.
