Craneflies are an often overlooked trout food. A version of this pattern was shown to me in my first summer of fly fishing. I will be forever grateful to that unknown angler for clueing me into craneflies. This pattern has been very effective on Black Hills streams, and has worked well on larger tailwaters such as the Bighorn. In recent insect sampling we have seen an increasing number of Cranefly larvae in Rapid Creek. Try this crane fly nymph pattern in sizes 4-10.
