The Olive Mohair Leech is a versatile and effective fly pattern that imitates a variety of aquatic prey such as leeches and small baitfish. This pattern features a body made of olive mohair yarn, which creates a lifelike texture and undulating movement in the water.

The Mohair Leech is a highly productive fly pattern in both stillwater and moving water environments. It can be used throughout the year, but it excels during periods when fish are actively feeding on leeches or when imitating small baitfish. This fly is particularly effective in lakes, ponds, and slow-moving rivers where leeches are a common food source for fish. Fish it with a slow, steady retrieve to imitate the movement of a leech swimming through the water. Alternatively, you can use a twitch-and-pause technique to mimic the erratic behavior of injured or fleeing baitfish.
