Stone Case Caddis Larva
Note: The trick to getting the gravel to stick to the hook shank is to coat hook shank with "Softex" glue and submerge hook into a container of gravel pieces. Let glue dry and remove hook from container. Lightly knock off stray pieces of gravel and then coat remaining gravel with another layer of "Softex" and let dry. Once dry, tie on body, legs and head.
