Coraebus rubi is a species of jewel beetles belonging to the family Buprestidae, subfamily Agrilinae. This beetle is present in most of Europe, in the Near East, in East Palearctic ecozone and in North Africa. It is quite common on Rubus species (hence the specific name), where larvae feed on roots and adults feed on leaves. It is considered a dangerous enemy of roses. The length of adults varies from 8 to 12 millimetres (0.31 to 0.47 in). They are easily recognizable for their black color with shades of gold and bronze-purple, as well as for their grayish irregular transverse bands on elytra.
