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.
