Tamarix (L.) was introduced to North America in the 1800s and has become an ecological dilemma because of its rapid spread. Control of the species has become top priority for many ranchers and land owners across the United States. Sul Ross State University at Alpine, TX has been part of a biological control project using Diorhabda (Brulle') as a method to reduce the biomass of existing saltcedar. While gathering observational data for the project at Big Bend Ranch State Park, another biological control agent, Coniatus splendidulus (Fabricius), was discovered. The species has been documented in other parts of the United States and Mexico where Tamarix sp. has spread.
