Bead Head LaFontaine Olive Deep Sparkle Caddis Pupa – Hook Size 12
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 caddis pupae drifting near the bottom.
Early-Stage Caddis Pupa Imitation – This pattern 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 mimics trapped air bubbles around the pupa, enhancing realism in the water.

This fly is most effective during spring through fall hatches when caddis pupae emerge and drift near the riverbed or mid-water column.
Is this pattern suitable for still or moving water?
This pattern works best in flowing water where caddis pupae drift naturally along the riverbed or mid-water column.

Jonathan Hemmings –
This fly performs well during early spring hatches. The olive color and sparkle yarn match the natural pupa drift perfectly. I’ve used it on several rivers and caught a few trout with it.
Jennifer Pullman –
The detail in the sparkle yarn makes it look very realistic. It’s a great match for mid-water drifts. I noticed it worked better in moderate current conditions.
Gordon Allan –
I’ve fished this pattern for over a year and it still holds up well. The bead head design keeps it stable in the water, and the olive color blends naturally with the riverbed.
