Deep Sparkle Caddis Pupa — Created by Gary LaFontaine in the mid-1970s after three years of scuba diving to observe live caddis behavior underwater; featured in his 1981 book Caddisflies, this pattern imitates the early emergence stage of pupae drifting near the bottom.
Early-Stage Caddis Pupa Imitation — Represents caddis pupae as they exit their cocoons and drift along the riverbed or mid-water column during spring through fall hatches; the sparkle yarn imitates trapped air bubbles around the pupa.

Boris Knox –
This fly performs well in clear streams during early spring. The olive color and sparkle yarn match the natural pupae drift perfectly. I caught several trout using it on a slow retrieve.
Christian Skinner –
The detail in the pattern is impressive. The sparkle gives a realistic look to the pupa’s surface. Works well in moderate current conditions.
Samantha Parsons –
I’ve used this fly in multiple rivers and it consistently attracts fish during fall hatches. The hook size is ideal for medium-sized streams.
Jessica Churchill –
The fly holds up well in water with some silt. The sparkle effect is subtle but effective, especially when the water is still.
Alan Springer –
Great match for early emergence hatches. The design is faithful to LaFontaine’s original pattern and works well with a slow, natural drift.
