The bee genus    Pseudoanthidium    is represented by nine species in Europe. Of these nine species,    Pseudoanthidium   nanum    is the most widespread, occurs mainly in xerothermic open habitats and creates nests in various cavity types. In this study, we provide information on the nest structure of this species in reed stalks and oak galls and about its parasitic species. We provide the first report of    P.   nanum    as a host of    Xylophrurus   augustus    (  Ichneumonidae  ). The biology of the much rarer related species    Pseudoanthidium   tenellum    is described here for the first time. This species occurs in terrestrial reed beds and wet meadows with the presence of reed galls and flowering plants in the family   Asteraceae   and is rare throughout its entire distribution area. This species nests inside reed galls induced by    Lipara    frit flies, and the nest structure is very similar to that of    P.   nanum   . We report new parasitic species of this bee, namely, the cuckoo bee    Stelis   punctulatissima   , the predator-inquiline    Gasteruption   nigrescens    and two parasitoids,    Leucospis   biguetina    and    Miltogramma   punctata   . This bee collects pollen mainly from wetland plants in    Bidens    and    Pulicaria   . We also describe mature larvae of both species. The larvae do not differ greatly from one another; only the shape of mandibles and sclerotisation of mouthparts are slightly different. Further research should address the ecological requirements of    P.   tenellum   , a poorly understood reed gall inquiline.
