The Cerambycidae – Cerambycids – Longhorns

The Cerambycidae family (Cerambycids – Longhorns or Capricorn beetles) – Latreille 1802 – includes an enormous number of genera. According to Wikipedia, there are 5,000 genera and 34,000 species spread across 13 subfamilies!

Characteristics

  • elongated body
  • parallel elytra
  • long antennae, often longer than the body
  • non-filiform, complex, segmented antennae

Members of the Cerambycidae family – Cerambycids – Longhorns live in old trees and especially in dead wood.

These beetles are impressive, mainly because they are either huge, several centimeters long, like the Great Capricorn beetle I encountered at the forest edge on a sidewalk, or they have a majestic appearance, such as Aristobia freneyi, which I saw in Khao Lak, Thailand in 2013, with its color, body spines, and “tufts” on the antennae.

A particularly special encounter was with the only one I actively searched for… after some research and a few tricks to locate it… I’m talking about Rosalia alpina, the Alpine Rosalia. Magnificent!!!! And what colors!!!!

These species are endangered due to logging and habitat destruction. Among the conservation efforts, it is essential to preserve areas with dead wood and tall cut trunks for their reproduction.
