Orgichneumon calcatorius (Thunberg, 1824) View in CoL

Notes

Not uncommon hibernating below bark, including the eastern Palaearctic ( Riedel 2018). Similar to Stenichneumon militarius and Ichneumon deliratorius . However, the white colouration is more extensive, notably on the orbits and the mesopleuron. The apical segments of the metasoma do not have a white spot. Historical data are notably scarce, which translates to 10 new country records as hibernators (on 14 countries). One uncertain record exists from Switzerland (GBIF) on 20. XII. 1990.
