The present invention relates to an insect breeding facility and to a method for the industrial scale production of mature larvae from egg-laying mother beetles, which mature larvae serve as protein rich food. The insect breeding facility comprises a spawning area with a number of spawning containers, wherein at least one spawn structure is provided in each spawning container. In the spawning area the mother beetles spawn their eggs in spawn structures, and insect food is provided to the spawning containers. The insect breeding facility further comprises a hatch area with a number of hatching containers, which are adapted to receive the eggs, larvae food and to allow harvesting of mature larvae. Periodically, a batch of spawn structures is removed from the spawning containers and replaced with new spawn structures, and the eggs of the batches of removed spawn structures are transported into a hatching containers.
