Rhaebus (from the Greek: ῥαιβός curved) is a genus of metallic
bean weevils in the subfamily
Bruchinae, and the only member of the tribe Rhaebini.[2][3][4] It is restricted to the Palearctic region.[4]
Appearance
Rhaebus beetles are small, measuring between 3-5 millimetres in length, and are metallic in colour, which is rare in members of the Bruchinae subfamily. Their bodies are elongated in shape, and the antennae vary.[5]

Rhaebus beetles feed exclusively on plants of the genus Nitraria, where their young also develop.[5][6][7]
