Pteronarcys dorsata (Giant Black Stonefly) Stonefly Nymph Pictures

Jason, you short video it shows a Pteronarcys dorsata nymph squirming around in a container filled with water. My recent observations finding Pteronarcys dorsata nymphs in the shallows and then dropping them back into the drift is they sink helplessly at the mercy of the current, no swimming or struggling. Often times on their backs while sinking towards the bottom.

I haven't tied a lot of stonefly nymphs. In most cases the river I fish don't really have a lot of stoneflies. Where would be the best place to look for stonflies. In fast running water.
