The Giant Stonefly can get as big as 40mm long and they begin their migration from the bottom of the river long before they actually come out on the banks to hatch. This movement to the banks creates a real opportunity for feeding trout and this big stonefly fly pattern is perfect for imitating these nymphs. Fish this stonefly as if it were moving along the bottom with very short strips. In black, brown.

Sizes: 8, 10.
