Overview

Ropalopus

*Ropalopus* Mulsant, 1839 — the "Club-legged Longhorns" — is a small genus of medium-sized cerambycids (8–18 mm) whose most striking feature is the distinctly clavate (club-shaped) femora that give the group its common name. Three species occur in Europe, out of six known from the western and central Palaearctic. Adults are encountered from late spring through summer, typically along forest edges where sycamore and other deciduous trees grow, and can be attracted to freshly dead wood or UV light. Larvae develop subcortically and into the wood of dying or dead branches, with development spanning one to two years.
