Bead Head LaFontaine Tan Deep Sparkle Caddis Pupa – 12 Flies Size 18
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 natural movement and visibility in the water.

Phil Wright –
This fly performs well during early spring hatches. The tan color and sparkle yarn make it stand out in the water, and it catches fish consistently on slow presentations near the bottom.
Grace Hardacre –
I’ve used this pattern on several rivers and it works well when the water is calm. The sparkle effect adds realism, and the size 18 fits perfectly for mid-water drifts.
Julia Roberts –
Great imitation of early pupa emergence. The fly moves naturally and fish take it on the first cast. Highly recommended for spring and fall caddis hatches.
Michael Ellison –
Felt like a natural match during a mid-morning drift. The sparkle helps it look lifelike, and it’s easy to tie with the bead head design.
