In this video, Greg ties a WD-40 fly – an effective Mayfly imitation. You can fish it as a dropper behind a nymph and adding a bead helps the fly get down quicker, especially in fast water. Tie the pattern in black to imitate Tricos, or in any other color to match midges and mayflies in your local waters.
