The adults grow up to 8–15 millimetres (0.31–0.59 in) and can be encountered from April through July, completing their life cycle in two years, as the beetles overwinter. The head and pronotum are black, while the elytra are reddish-brown at the front and blue-gray at the back, with three oblique light stripes in the middle. The body is hairy and has a bluish tone.
This beetle is present in most of Europe, in Turkey and in North Africa. They are widely polyphagous on broadleaved timber and extensive lists of hosts have been compiled including Oak (Quercus), Beech (Fagus), Hawthorn (Crataegus), Hazel (Corylus), Lime (Tilia), Dogwood (Cornus), Pear (Pyrus malus), Birch (Betula), Alder (Alnus), Cherry (Prunus), Spindle (Euonymus) and Persimmon (Diospyrus).
