== 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.<ref name=":1" />

== Diet and life cycle == ''Rhaebus'' beetles feed exclusively on plants of the genus ''Nitraria'', where their young also develop.<ref name=":1" /><ref name=":2" /><ref>{{Cite journal |last1=Lopatin |first1=Igor |last2=Chikatunov |first2=Vladimir |name-list-style=amp |date=2000-07-31 |title=''Rhaebus amnoni'' n. sp. – The first representative of the Central-Asian genus ''Rhaebus'' in Israel |url=https://www.zobodat.at/pdf/Mitt-Int-Ent-Ver_25_1-2_2000_0031-0034.pdf |journal=Mitteilungen des Internationalen Entomologischen Vereins |volume=25 |pages=31–34 |via=Zobodat}}</ref>
