( Latin: Tenebroides mauritanicus)
Originally an African species, this beetle has now spread to almost all parts of the world.
It is found particularly in grain warehouses, silos and mills. The larvae live hidden away, feeding on corn and flour, but also live to a certain extent as predators on other insects.
The species is probably not very common in Europe but may be a serious pest in flour mills because it destroys the sieves by biting holes in them. Development is rather slow, so this species should never become a problem in private households.
