The Cascade Timberline Grasshopper, Prumnacris rainierensis, is a flightless alpine species of the Oregon and Washington Cascade mountains. The photos shown here were taken in the Paradise area of Mt. Rainier National Park.

The Cascade Timberline Grasshopper is related to Nisquallia olympica (see Insect menu) and occupies a similar ecological niche, above treeline. Though flightless, at least some Cascade Timberline Grasshopper adults have rudimentary wings.
