Umpqua Jiggy Caddis Pupa Mercer Olive - #14

This modern caddis pupa takes the proven Mercer concept and puts it on a tungsten-loaded jig hook. Size 14 with an amber and yellow body gives a natural caddis look that works well in many European rivers, from freestone streams to regulated tailwaters. The jig hook and slotted tungsten bead get the fly down quickly and help it ride hook-point up, which reduces snagging and suits both Euro nymphing and indicator setups.

Use it when fish focus on caddis emerging near the bottom or when a mayfly pattern just stops working. The subtle flash and soft movement suggest a living pupa rather than a bright attractor, so it fishes well even in clear water and on pressured trout. A solid choice as the heavy anchor fly in a nymph rig or as a single nymph under a light strike indicator.
