Cerambyx welensii is a species of beetle in the family Cerambycidae (longhorn beetles). This species demonstrates sexual dimorphism, characterized by physical and behavioral differences between males and females, due to their varying body and antenna sizes.{{Cite journal |last=Miroshnikov |first=A.

Biology
Larvae of these beetles are xylophagous. They mainly feed on downy oak (Quercus pubescens), evergreen oak (Quercus ilex) and cork oak (Quercus suber). These longhorn beetle are considered a pest of oaks.{{cite journal |last1=Torres-Vila |first1=L. M. |last2=Mendiola-Diaz |first2=F.
