Angelica sylvestris
Adults of these endoparasitoid flies can be found from March to May and in October-November. They mainly feed on nectar of "Angelica sylvestris". The females lay their eggs close to the ovations of the host species, especially "Hyphantria cunea", "Orthosia cerasi", "Dypterygia scabriuscula" and "Sphinx pinastri"). When the larvae of the host are born, the larvae of these flies feed on the larvae of the host.
