Everything seems consistent with P. biloba, the "Knobbed Salmonfly." Unlike dorsata, it is usually found in small streams and headwaters where it is a real mouthful for the little trout. Typical salmonfly nymph ties tend to be likewise, so I usually choose to imitate the younger, smaller generations of nymphs.
