The Net Builder Caddis Nymph pattern is a great caddis larvae pattern for all types of bodies of water. This is an absolutely top choice for a caddis larva imitation.
Us at Zinger Fishing use them all the time in hopper dropper rigs. These little guys could be fished under a dry caddis or used in a euro nymphing rig which is my favorite.
The Net Builder Caddis Nymph is great for trout and whitefish. It is a must-have in the fly box.
