The Sparkle Caddis Pupa in tan imitates the caddis pupa stage — the phase when caddis are most vulnerable and trout feed on them heavily. The tan coloring matches many common caddis species.
Fish it subsurface just under the surface film or near the bottom during caddis emergences.
This pattern earns its place in the box year-round; when no hatch is visible, trout are almost always eating something that looks like this below the surface.
