A material table for the prince nymph is available on my 12/03/2011 post on this blog. The prince nymph enjoyed a resurgence in my fly box during the past two seasons, and a main reason is the success it delivered during green drake hatches. Apparently a size 12 peacock imitation is a close approximation of the nymph stage of the large western green drake mayflies. Check out my South Boulder Creek 08/15/2019 post for an example of prince nymph productivity in advance of a green drake hatch.
The other prime situation that creates prince nymph success is the egg laying stage of a grannom hatch. A size 14 prince tied on a curved scud hook historically delivered superior results on the Arkansas River and other western streams during the April and May caddis event. My post of 11/17/2018 does a nice job of describing these prince nymph applications, and it also describes some improvements that I introduced to my tying technique. Mounting the white horns with the points of the biots extending beyond the eye of the hook and then bending back to lock them down has dramatically improved the durability of my prince nymphs, particularly the larger sizes.
The new found effectiveness of the size twelve prince nymph resulted in some depletion of my inventory, so I tied four new models to elevate my count to ten. In addition I manufactured four size 14’s and refurbished a pair of size 16’s. I am confident that my supply will be adequate for the 2020 fly fishing season.
