Thirty-nine species of Eupelmidae belonging to seven genera and three subfamilies are listed. Ten of them are new for the fauna of Bulgaria and three for the Balkan Peninsula. New hosts and plant associates are established. Phenology of 37 species is studied. The highest imaginal activity is recorded in late spring (May), summer (June, July, August) and early autumn (September), and the highest variety of species is established during the three summer months, especially in August. The longest imaginal activity among the genera is observed in Eupelmus (seven months) and Anastatus (six months). The studied species are divided into six phenological groups and among them the summer phenological group is the most numerous. As a result of this study, 20 species (51.2 % of the total number) are found in a habitat of type 6210 Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia). About 77% (30 species) of the species are recorded only in the oak zone. Key words: Eupelmidae, Bulgaria, Balkan Peninsula, faunistic data, new hosts and plant associates.
