Opeia obscura
obscure grasshopper
Opeia obscura, commonly known as the obscure grasshopper, is a slant-faced grasshopper in the family Acrididae. It is widely distributed across the grasslands of North America and into Central America. The species is a specialist feeder on blue grama grass (Bouteloua gracilis) and is considered a late-hatching grasshopper, with eggs typically hatching in June. While it can contribute to rangeland damage during grasshopper outbreaks, populations rarely reach outbreak densities independently.
