Appearance
The adults grow up to 6 – 12 mm and can be encountered from May through August, completing their life cycle in two year. The imagos fly the second year.Head, pronotum and elytra are brownish and the elytrae are crossed by light stripes, as this beetle imitates, for defensive purposes, like other species of the genus Clytus, the chromatic variety of wasps. Bicolor tibiae distinguish ''Clytus rhamni bellieri'' subspecies.
Food
They are polyphagous in deciduous trees. Larvae mainly feed in the dead wood of small branches of ''Rhamnus'' , ''Castanea'', ''Quercus'', ''Ficus'', ''Ulmus'', ''Pyrus'', ''Prunus'' species. The adults are very common flower-visitors.References:
