This invention provides a device for collecting and hatching black soldier fly eggs, comprising several first mesh nets, second mesh nets, and a hatching layer arranged sequentially from top to bottom. The hatching layer is a polygonal structure with an open top. This invention combines the functions of collecting and hatching black soldier fly eggs. Adjacent egg collection chambers are effectively isolated by the corrugated plate itself, preventing them from sticking together and reducing the number of black soldier fly eggs piled up.
