Overview
Diorthus
*Diorthus* Gahan, 1906 is a small, poorly known genus of longhorn beetles confined to North Africa, where adults are associated with oak and beech woodland from sea level to around 800 m elevation. Beetles are elongate-cylindrical, ranging from 15 to 28 mm, and exhibit variable coloration and patterning. Adults are diurnal to crepuscular, with a flight period spanning May through August, and are attracted to fresh dead wood and UV light. Larvae develop subcortically before entering the wood, with development spanning one to three years.
