Tetramesa romana, commonly known as the arundo wasp, is a species of wasp native to France and Spain. As its common name implies, the species feeds on Arundo grass. These wasps have been imported to North America in biological control efforts surrounding Arundo donax, but their efficacy has been disputed.Showler, Allan T.; Osbrink, Weste L.A. (25 October 2018.) "The arundo wasp, Tetramesa romana, does not control giant river reed, Arundo donax, in Texas, USA". Entomologia Experimentalis et Applicata. The species reproduces parthenogenically, with females laying eggs into the stems, resulting in developing larvae forming stem galls.
