Abstract

Data on the bionomics ofDryudella stigma(Panzer, 1809) in Poland are presented. The larva is described for the first time for a EuropeanDryudella, and second in the world with only larva ofD. immigransdescribed before. The egg stage lasts 2–3 days, and the larval stage 11–14 days. The praepupal stage lasts the longest time and overwinters in a cocoon from mid-July to the end of May. The female provisions with an average of seven bug nymphs per cell, mainly ofAelia acuminata(Linnaeus, 1758) (Pentatomidae), less oftenCeraleptus lividusStein, 1858 (Coreidae) andCorizus hyoscyami(Linnaeus, 1758) (Rhopalidae). Nests are built in sandy, shaded areas and consist of the main burrow, 10–12 cm long, and one terminal cell. Males are most often found in sunny areas. Adults visitAchillea millefoliumL., Asteraceae, as the main source of nectar.
