Crane Fly Larva

The Cranefly Larva Nymph is a highly effective fly pattern that mimics the larval stage of the cranefly, a vital food source for trout in many rivers and streams. These larvae are large, worm-like creatures, typically one to three inches long, making them a high-protein target for fish. This fly shines during periods of high water or runoff when cranefly larvae are naturally dislodged from the riverbed and drift downstream. Its realistic size and fat profile make it an irresistible meal for hungry trout, particularly in turbulent waters where these larvae are abundant.

Fish the Cranefly Larva Nymph during high water conditions or after heavy rains when natural larvae are washed into the drift. Use a weighted version or add split shot to your leader to ensure the fly reaches the bottom where trout often feed on dislodged prey. Drift it through deeper runs, seams, and eddies with a dead drift under an indicator, or tightline nymph for better sensitivity in faster currents. For increased effectiveness, pair it with a smaller nymph as a dropper to imitate a natural multi-food drift. Pay close attention to subtle takes—trout often inhale these big meals softly!
