Alderfly Wet

The Alder Wet Fly is a historic pattern in fly fishing, dating back over 500 years, and is one of the earliest documented fly designs. Known for its simplicity and effectiveness, the Alder Wet Fly has been used for centuries to imitate the alder moth, which is typically found near riverbanks and shaded waters. Traditionally tied with a dark body—usually deep brown or black—and gray-brown wings, it closely resembles the natural insect both in color and form. The fly is generally tied on hooks in sizes 10 to 14, which closely match the alder moth’s natural size.

The Alder Wet Fly is most effective when fished in the late spring and summer months, particularly during alderfly hatches near streams and rivers. Fish it on a downstream swing or with a slow, steady retrieve to mimic the natural movement of an adult alderfly or emerging caddis. Target shaded areas near overhanging trees, grassy banks, or where debris collects in the water, as these are prime habitats for alderflies. For extra effectiveness, let the fly rest momentarily during the swing or retrieve—this often triggers strikes from opportunistic trout waiting for an easy meal. Pair it with a heavier nymph or wet fly on a dropper to explore multiple feeding levels.
