How It’s Tied
The Sparkle Pupa is typically tied on a curved or straight-shank hook. The body, made from dubbed fur or synthetic materials, creates a fuzzy, segmented shape that mimics a caddis pupa.
A defining feature is the translucent "bubble" of Antron or similar material tied over the body. This imitates the gas bubble that forms around a real caddis pupa during emergence—giving the fly its name and effectiveness.
To finish, a soft hackle is added at the collar, simulating the legs and antennae of the emerging insect.
What It Mimics
The Sparkle Pupa replicates a caddis pupa just before it breaks through the water’s surface. The translucent gas bubble imitation is a brilliant touch, making this fly exceptionally effective.
Where It’s Used
This fly excels in rivers and streams during caddis hatches. It’s designed to be fished in the surface film, perfectly imitating a pupa on the verge of emergence.
