(Some breeders dedicate a whole room or greenhouse to species such as the hummingbird/bee hawks -macroglossinae) once you have a male and female emerged put them into the pairing cage. You can add more but overcrowding is not recommended as the males not paired can interfere with already coupled moths. Some Hawks are day flyers and will require bright sunshine before taking flight. Those that fly after dark fly at various times depending on the species. Femalrs tend to begin there "calling" (release of phreomone) on the second night of emergence.
