I guess with all the emphasis on bugs and other invertibrates I never thought trout would eat a snail. On my last trip to the White river the most successful pattern I used was a size 14 olive bead head flashback. It looked almost identical to the size, color and general shape of the snails that were among the rocks. The snails seemed extremely prolific at the Rim Shoals area where we did most of our fishing. Am I making an incorrect connection? There was a caddis hatch almost every evening we were there so I suppose it might resemble another nymph instead of a snail. Any insights would be greatly appreciated.
