Designed as a mayfly, this would work for caddis, too. Swapped out the CdC wingcase/emerger for foam and Hi-Viz for better optics.
hook - WFC Model 11 #12
thread - Danville 6/0 brown
abdomen - biot tan/yellow
wingcase - 1mm foam black
indicator - Hi-Viz hot orange
thorax - deer hair (loop dubbed/trimmed)

Scott
