This is a cased caddis larva pattern tied in the Czech style. This nymph is tied on a jig hook with a slotted tungsten bead that causes it to bounce along the bottom with the hook point riding up. Cased Caddis patterns are very effective, especially in freestone streams. Fish this fly on point, with a smaller offering above it.
This is a straight forward czech nymph tying sequence, nothing earth shattering. Weight and body taper are formed by lead tape. The color combination on this pattern has been particularly effective. This pattern can also be tied with a tungsten bead. Tie in sizes 10-16.
