Pallid-winged Grasshopper

The pallid-winged grasshopper (*Trimerotropis pallidipennis*) is one of the most widespread grasshopper species in North America. They are commonly found in arid regions, expansive deserts, and open gravelly areas ranging from southern Canada all the way down to Argentina. They thrive in hot, dry environments with sparse vegetation.

As an opportunistic herbivore, this grasshopper feeds on a wide variety of desert grasses, low-growing shrubs, and broadleaf weeds. During major population outbreaks, they can become significant agricultural pests, devouring alfalfa fields and rangeland crops. They are known to consume whatever plant life is locally abundant in their harsh habitats.

This species is recognized for its highly variable coloration, which perfectly mimics the soil and rocks of its specific habitat to hide from predators. Their bodies can range from pale gray to brown or tan, seamlessly blending into the gravel and sand of their desert environments. When they land after flying, their pale hindwings are tucked away, instantly making them invisible against the ground.

Yes, under severe overcrowding and food shortage conditions, these grasshoppers can form massive swarms and migrate over long distances. During these intense migrations, they travel in huge, flying black clouds that can cause severe damage to agricultural crops along their path. These swarms are often driven by sudden changes in weather and a lack of vegetation.
