Distribution . Japan ( Hokkaido , Honshu, and Izuoshima Is.*); Taiwan and widely distributed in Holarctic region. Bionomics . Unknown in Japan . Saturnia pavonia (Linnaeus, 1758) ( Lepidoptera , Saturniidae ) has been recorded from Europe ( Scopoli, 1763 ). This host record is doubtful because the main host of Stilpnus is Diptera . Remarks . This is the first record of this species from Izuoshima Island.
