Cantharocnemis
Cantharocnemis
*Cantharocnemis* [auct., verify] is a large, robust longhorn beetle of the subfamily Prioninae, reaching 20–40 mm in body length and presenting a distinctly flattened, dark brown appearance. The genus is primarily Afrotropical in distribution, extending into eastern and southern Africa and Arabia, where adults are active nocturnally between June and September. Attracted powerfully to UV light, these beetles inhabit forested and woodland habitats from sea level to approximately 1,500 m altitude. Larvae develop deep within the heartwood of dead or dying trees, particularly Acacia and other tropical trees of the family Fabaceae, over a prolonged period of two to five years.
