Synanthedon stomoxiformis is a moth of the Sesiidae family. It is found in most of Europe (except Ireland, Great Britain, the Netherlands, Belgium, Fennoscandia, Estonia and Latvia) and the Middle East. The wingspan is 22–31 mm. Adults are on wing in June and July. The larvae feed on the roots of Frangula alnus and Rhamnus cathartica., although there are also records for Mespilus germanica, Juglans regia and Prunus and Quercus species. In springtime, the larva constructs a very characteristic exit tube from the root to ground level.
