LaFontaine Olive Caddis Pupa – Sparkle Nymph (3 Pack, Sz 18)

A proven caddis pupa pattern grounded in real underwater observation. The Deep Sparkle Caddis Pupa was developed by Gary LaFontaine after years of scuba diving to study live caddis behavior beneath the surface. Featured in his influential 1981 book Caddisflies, this fly imitates the vulnerable early emergence stage when pupae drift near the bottom before rising to hatch. The signature sparkle yarn sheath mimics the trapped air bubbles surrounding natural caddis pupae, creating subtle flash and lifelike movement that trout key in on during active hatches. With its natural profile and added weight for sink rate, this pattern excels in freestone rivers, tailwaters, and mountain streams from spring through fall. Classic Gary LaFontaine Design: Inspired by real underwater caddis research Early-Stage Pupa Imitation: Mimics drifting caddis pupae before emergence Sparkle Yarn Construction: Simulates trapped air bubbles for added realism and attraction Weighted Profile: Helps the fly reach and stay in the strike zone Versatile Presentation: Fish dead drifted, swung, or under an indicator Proven Trout Producer: Effective for brown, rainbow, brook, and cutthroat trout A practical and highly effective addition to any nymph or wet fly box, the Deep Sparkle Caddis Pupa shines whenever trout are feeding below the surface during caddis activity.
