The developmental life history of Spalangia cameroni Perkins is presented, with observations on physiology of ovum formation, and sperm translocation through the male reproductive system. Pertinent aspects treated in detail are host-feeding and selection, oviposition, superparasitization, length of developmental stages, oöcyte development, ovisorption, and sperm activation. Of particular interest are the interinvolvement of host-feeding and oviposition, the high moisture requirement for embryonic development, the 100+ feeding punctures made by a larva, the prolongation of female pupal development with respect to the male, the deposition of partially resorbed eggs, the discovery of 2 chambers in the seminal vesicle, and the short time that the testes function.
