Cerambryx cerdo

In this Saturday episode of Talking Trees, we take a closer look at the Cerambyx cerdo, also known as the great capricorn beetle—a striking and ecologically significant member of the longhorn beetle family.

We discuss:

Its scientific classification and broad geographic range across Europe, Asia, and North Africa, with historic extinction noted in the UK
The beetle’s distinctive appearance, including body size, dark coloration, and the notable difference in antenna length between males and females
Details of its ecology and life cycle, which spans 3–5 years and involves larval development within damaged wood of oak trees, making it dependent on aging or stressed habitats
Signs of infestation in host trees and the ecological importance of deadwood habitats for sustaining its population
Its status as a vulnerable species, highlighting the urgent need for conservation efforts and habitat protection, particularly in oak-dominated landscapes

The Cerambyx cerdo is more than a curiosity—it’s a reminder of the complex, interdependent lives supported by our oldest trees.
