Tetramesa romana is a non-native wasp that has been introduced in Texas and California (and possibly elsewhere in riparian environments in N. America, to control the non-native giant weed, Arundo donax.

Patrick Moran explains in the UC Weed Science blog that the emerging adult wasps "chew distinctive round exit holes which can be observed to track wasp populations in the field." And, Valle Rogers, who assisted Moran on the biocontrol project, writes in iNaturalist that "Some of the largest galls are actually of young main shoots just above the ground."
