Stonefly Species Pteronarcys princeps

These are pretty much always called Ebony Salmonfly.

This species takes over for Pteronarcys californica at higher altitudes and smaller waters. Because of their habitat preferences, they never achieve the population densities of californica. This and their smaller size are the only differences as they are similar in both appearance and behavior.
