The present invention relates to an apparatus for breeding fly larvae, and more particularly, to an apparatus for breeding fly larvae in which a breeding chamber is divided into multiple square sections to enable larvae to progressively grow and to complete the growth thereof, the larvae with the exception of those having escaped to an emergency chamber, are collected, and the larvae having escaped to the emergency chamber emerge as flies and are moved to a fly habitat chamber arranged above the breeding chamber to live and oviposit into the breeding chamber, and the above-described process is repeated so as to automatically breed larvae. To this end, the apparatus for breeding fly larvae of the present invention comprises: a fly habitat a larvae-breeding area installed in the fly habitat and a lid covering an upper portion of the larvae-breeding area, wherein the larvae-breeding area includes a pillar unit installed on the bottom of the fly habitat, and multiple breeding chambers installed in the pillar unit such that the breeding chambers operate independently.
