The Sparkle Pupa Tan Emerger pretty much does it all. An absolutely deadly pattern during the caddis hatch. It imitates caddis just before they leave the water and fly away. Trout often have a small window to eat these flies and attack them with urgency. Fished dead drift in slower waters is a great approach. They fool trout time after time and continue to be one of the top guide’s choice fishing flies for caddis hatches.
