The ovipositor of the female (Leucospidae) is sometimes very short, otherwise it is curved and extends along the dorsal part of the abdomen. The males have the peculiarity that the segments of the metasoma form a kind of capsule or shell. The female deposits an egg on or near the prey. When the larva hatches, it first seeks out and kills any competitors and only then begins to feed on the host. The objective of this article is to deal with the animal behavior of the Leucospidae Family. For this, a bibliographic survey of Leucospidae was carried out in the years 1883 to 2022. Only complete articles published in scientific journals and expanded abstracts presented in national and international scientific events were considered. Data were also obtained from platforms such as: Academia.edu, Frontiers, Qeios, Pubmed, Biological Abstract, Publons, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic and Science.
