Pallid-winged grasshopper

The pallid-winged grasshopper (Trimerotropis pallidipennis) is a common grasshopper of the family Acrididae, native to the deserts of western North America. They are more active during the summer months, and their pale, mottled coloration makes them hard to see against surfaces such as the granite often found in the gravel of dry river beds. They grow to be 37 mm (1.5 inches).

Experts following the swarm estimated 20-30 grasshoppers for every square foot of land in the Phoenix Metro Area. Several business remained closed for several days and traffic accidents severely increased during the time.

When morning Rush Hours began, clouds of grasshoppers could be seen in the sky.
