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.

The olive color matches natural caddis pupae well. The sparkle yarn adds a realistic touch that makes the fly stand out in the water. I’ve used it during spring and fall and caught several trout on it.

This fly is a faithful imitation of the early pupal stage. The hook size 14 works well with my rod setup. The sparkle effect is subtle but effective during low light conditions.

I bought this after reading about Gary LaFontaine’s research. The attention to detail in the design is impressive. It’s been a reliable pattern during mid-water drifts in clear streams.
Owen Hudson –
The 6-fly pack is sufficient for a few trips. The material holds up well after multiple casts. I noticed better strikes when using it near the bottom during early morning.

The fly looks authentic and performs well in both still and flowing water. The sparkle detail is just right—doesn’t overpower but adds realism. Highly recommend for caddis pupa fishing.
