Abstract: 
What little is known about the biology of the Trigonalidae Family indicates a remarkably unlikely life story: in nearly every known species, females place thousands of tiny eggs, either "squeezing" them around the edges or injecting them inside the leaves. The egg must then be consumed by a caterpillar. Once inside the caterpillar, the trigonalid egg hatches and attacks any other parasitoid larvae (including its siblings) on the caterpillar, or waits until the caterpillar is killed and fed to a wasp larva, which then attacks. The aim of this manuscript was to carry out an inventory of the Family Trigonalidae (Insecta: Hymenoptera) related to its biogeography, bioecology, habitat, geographic distribution, taxonomy, life cycle, phenology and taxonomic and conceptual aspects of the Family, Subfamilies and Species. For this, a bibliographic survey of Trigonalidae was carried out in the years 1905 to 2021. 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, Science and ERIC.
