The distribution and ecology of all twenty species of Hylaeus Fabricius, 1793 occurring in The Netherlands are discussed. A comprehensive key (in English) to the species of The Netherlands and adjacent areas is given. The maps illustrating the distribution within The Netherlands are based upon ca. 10,000 specimens. The collection of the Leiden Museum and literature sources were used in preparing the maps showing the distribution in Europe. Two species, H. pfankuchi and H. styriacus, have not been recorded from the Netherlands since 1950.
