LaFontaine Olive Caddis Pupa – Sparkle Nymph (12 Pack, Sz 12)

A legendary caddis pupa pattern refined through real underwater research. The Deep Sparkle Caddis Pupa was developed by Gary LaFontaine after years of scuba diving to observe live caddis behavior beneath the surface. Featured in his influential 1981 book Caddisflies, this pattern imitates the vulnerable early emergence stage when pupae drift near the bottom before rising to hatch. Its 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. Combined with a weighted design and natural buggy profile, this fly excels in freestone rivers, tailwaters, and mountain streams from spring through fall. Classic Gary LaFontaine Pattern: Inspired by real underwater caddis behavior Early-Stage Pupa Imitation: Mimics drifting pupae before emergence Sparkle Yarn Construction: Simulates air bubbles for added realism and attraction Weighted Design: 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.
