Distribution.

Species of temperate-cold zones of the Palearctic region, widespread in Europe (excluding the Balkan Peninsula), Russia, Turkey, eastwards to Korea and Japan ( Yu et al. 2012). From Europe it has been introduced in Canada from 1956 to 1958 and from 1979 to 1981 to control the winter moth Opheroptera brumata (Linnaeus, 1758) ( Lepidoptera , Geometridae ) and has been reported as being established there ( Carlson 1979, Barron 1989).

Host range.

Yu et al. (2012) list 58 species, mostly belonging to the Lepidopteran family Geometridae (27 species). Further records include Tortricidae (8 species), Yponomeutidae (7), Noctuidae (5), Lasiocampidae , Nolidae (2 species each), Pyralidae , Thyatiridae , Notodontidae , Lycaenidae , Erebidae ( Lymantria dispar (Linnaeus, 1758)), and Diprionidae ( Hymenoptera Symphyta) (1 species each).

Ecological role.

This larval-pupal koinobiont endoparasitoid emerged from overwintering pupae of L. botrana and Eupoecilia ambiguella ( Hübner, 1796) ( Stellwaag 1928, Thompson 1957) in Italy (South Tyrol), France and Germany and Sparganothis pilleriana (Denis & Schiffermüller, 1775) ( Lepidoptera Tortricidae ) in France ( Stellwaag 1928). These hosts are not included in the list of Yu et al. (2012). Another species of the same genus, Agrypon anxium (Wesmael, 1849), is reported on the first generation larvae of EGVM in Switzerland and France ( Moreau et al. 2010), while A. minutum (Bridgman and Fitch, 1894) has been obtained by E. ambiguella in France and Switzerland and by S. pilleriana in Germany ( Villemant et al. 2011).

Taxonomic notes.

After its introduction in Canada, A. flaveolatum was confused by some American authors ( Carlson 1979, Dasch 1984) with similar Nearctic species belonging to the same genus ( Barron 1989).
