Bead Head LaFontaine Olive Deep Sparkle Caddis Pupa – 6 Flies Hook Size 16
Created by Gary LaFontaine in the mid-1970s after three years of scuba diving to observe live caddis behavior underwater, this pattern is featured in his 1981 book Caddisflies. The Bead Head Deep Sparkle Caddis Pupa imitates the early emergence stage of pupae drifting near the bottom during spring through fall hatches.
Early-Stage Caddis Pupa Imitation – This fly represents caddis pupae as they exit their cocoons and drift along the riverbed or mid-water column. The sparkle yarn mimics trapped air bubbles around the pupa, enhancing realism in natural conditions.

Victor Thomson –
This fly performs well in slow-moving streams during early spring. The olive color and sparkle yarn match the natural pupae perfectly. I’ve used it successfully on several trout runs and it’s a reliable pattern for bottom drifts.
Colin Ball –
The detail in the sparkle yarn adds a realistic touch. It’s easy to tie and matches the behavior of actual caddis pupae. Works best in moderate current conditions.
Megan Wallace –
I’ve tied dozens of these flies and they catch fish consistently. The hook size 16 is ideal for small to medium streams. The pattern is true to LaFontaine’s original design and very effective in fall hatches.
