Pediobius brachycerus (Thomson, 1878) (Hymenoptera: Eulophidae): A Re-discovered Parasitoid in the Polish Fauna with A New Host Record

Abstract

Pediobius brachycerus (Thomson, 1878), a hyperparasitoid of spider egg sacs, is reported from Poland with abundant distribution data. It has been mostly noted from wet and open habitats. Clubiona stagnatilis Kulczynski, 1897 and Argiope bruennichi (Scopoli, 1772) are recorded as its primary hosts, the former species for the first time. The host associations of P. brachycerus are summarized and briefly discussed
