In this paper, we provide an overview of the seed chalcid wasps Bootanomyia spp. and Megastigmus spp. (Hymenoptera: Megastigmidae) in both Belgium and the Netherlands. Sixteen species, including six non-natives to Europe, are reported after checking over a thousand specimens. The European species Megastigmus aculeatus (SWEDERUS, 1795) and M. suspectus BORRIES, 1895 are reported for the first time in Belgium. The European species Bootanomyia stigmatizans (FABRICIUS, 1798), Megastigmus rosae BOUČEK, 1971 and Megastigmus strobilobius RATZEBURG, 1848, and the Nearctic species Megastigmus atedius WALKER, 1851 and Megastigmus lasiocarpae CROSBY, 1913 (only the second report in Europe) are new for the Netherlands. Novel insights are offered on the ecology, morphology and phenology of Megastigmus aculeatus, Megastigmus nigrovariegatus and Megastigmus rosae
