Summary Invertebrate conservation translocations are the intentional movement of species into previously uninhabited locations (introduction), or areas where species have gone extinct (reintroduction), or supplementation of populations to mitigate extinction risk (restocking). We aimed to review global translocations of invertebrate species, identify species traits and features of projects (e.g. system type, numbers of individuals released, reproductive mode)that may affect translocation success, and to explore potential similarities between successful conservation translocations and invasive invertebrate species. Translocation projects differed widely in methodology, level of detail reported, and their evaluation of success. We defined success as some degree of survivorship and/or evidence of reproduction during projects, based on the IUCN Species Survival Commission objectives and previous translocation research. We collated and summarized the results of 514 translocation projects that represented 344 unique invertebrate species. Over 90% of all conservation translocations were species from four classes – Anthozoa, Bivalvia, Gastropoda and Insecta. Generalised linear models that included life history traits and translocation characteristics showed that translocation success was related to traits including species growth type, reproductivemethod, ecosystem type, and parental provisioning. We recommend future translocation projects include standardised reporting, with a minimum set of life history and methodological characteristics, and appropriate monitoring and reporting of outcomes. This information will help guide refinement in invertebrate translocations and improve conservation outcomes
