Creosote Bush Grasshopper
Bootettix argentatus is a slant-faced grasshopper in the Acrididae, commonly known as the creosote bush . The exhibits extreme dietary specialization, feeding exclusively on the creosote bush Larrea divaricata. It is distributed across arid regions of the southwestern United States, Mexico, and Central America.

More Details
Extreme dietary specialization
The monophagy of Bootettix argentatus on Larrea divaricata is notable; creosote bush produces toxic resins that deter most herbivores, suggesting this possesses biochemical adaptations to process these compounds.
