Trimerotropis pallidipennis
Pallid-winged Grasshopper, Pallidwinged Grasshopper
Trimerotropis pallidipennis is a moderately-sized bandwinged grasshopper with the widest distribution of any bandwinged grasshopper in the New World, ranging from southwestern Canada to Argentina. It is primarily a desert and semi-desert species that exhibits sporadic irruptive population outbreaks in western North America, during which it becomes a significant agricultural pest. The species possesses strong flight capabilities that enable long-distance dispersal and migration from deteriorating habitats. Population irruptions have been documented in Arizona, California, New Mexico, and Utah, with outbreaks typically lasting one to two years.
