Common name: Darkling beetles.
A family of about 20,000 described species of dark (“darkling”) beetles (Coleoptera) that may be apterous or whose elytra are absent. The dark-brown larvae possess a tough integument and are commonly called false wireworms. Adults and larvae often feed on the same food, including dung, weakened trees and in granaries. Species of Tenebrio and Tribolium, and Tenebroides mauritanicus are cosmopolitan pests of stored products.
