Best Wet Flies For Trout – Your Complete Wet Fly Guide


Article Categories: Fishing | Fishing Tips
Article Tags: Fishing Tips | Fly Fishing

One of the highlights of the fly fishing process is choosing just the right fly. There is a real art to figuring out just what the fish want to eat and having a lure that matches their precise tastes. Trout are simultaneously voracious and picky, a paradox many trout anglers have noted over the years, and so when you’re out on the water, it helps to have a variety of flies to choose from.

Fly fishing flies can be divided into two types: dry flies, which sit on top of the water, and wet flies, which sink into the water column. Today, we’re going to be discussing wet flies and which ones you should always keep in your fly box.

You should bring several of your favorite patterns. Fly loss is a common occurrence, especially when nymphing or otherwise fishing wet flies. Underwater hazards like logs and other debris can steal your fly, or you may lose a fly to an unraveled knot or a snarled line you have to cut. So make sure to bring a couple of copies of any of the patterns in this article on your next fishing expedition!


Choosing The Best Wet Flies for Trout

There are several types of wet flies you can use. The first type we will discuss is emergers, a fly that mimics an emergent insect (a pupated insect that is swimming upwards towards the water’s surface) or sometimes a drowned nymph or adult rising to the surface.

Nymphs are another type of wet fly that many anglers swear by. Nymphs are tied on very small hooks and are often fished with two nymphs on the line under a dry fly or other indicator. When choosing flies for trout, you need to know about local entomology and try to match the hatch. Specifically, you need to think about what types of insects are hatching and are in their aquatic states. You aren’t trying to match adult insects in many cases here; instead, you’re mimicking the larval insects. If you’ve ever wondered why it’s called nymphing, this is why– the larval state of an aquatic insect is often called a nymph.

Streamers are another great option for wet flies. Streamers mimic the action of an animal swimming in the water. This could be annelids like worms and leeches, crayfish, insects that have been swept in off of the bank, or baitfish.

Now that you have a general idea of what the different types of flies can do, let’s look at the must-haves for your fly box.


Best Emerger Flies for Trout Fishing

These flies should be fished above the bottom, since they mimic insects that rise in the water column. If you’re fishing a two-fly setup, an emerger makes a great second fly behind a nymph pattern lead fly.


Barr Emerger

Barr EmergerDeveloped in 1975, this emerger pattern came about after PMD (pale morning dun mayflies) patterns failed to attract trout. John Barr set up this pattern to mimic the emergent stage of that mayfly, although many mayflies look similar at this stage.

  • Imitates: Mayfly emergers
  • Typical Size: 16-22
  • Variations: Color variations to match local mayflies, including the popular blue-winged olive

Best Nymphs for Trout Fishing

Ask any fly fisher what the best nymphs for trout fishing are, and you will get a variety of answers. There are lots of great nymphs to choose from.


Hare’s Ear

Hare's Ear Nymph

Hare’s Ear Nymph

The Hare’s Ear is one of the most recognizable wet flies. It has a cult following; there are some anglers who refuse to use anything else. Since the colors don’t mimic any specific species of mayfly– just mayfly larvae in general– you can use this fly if any species is present in the water.

  • Imitates: Mayfly larvae
  • Typical Size: 10-18
  • Variations: Gold-ribbed Hare’s Ear

The Best Scuds and Sowbugs for Trout Fishing

We’re going to discuss scuds and sowbugs separately from other nymphs because of their year-round utility. Scuds and sowbugs aren’t insects– they’re tiny crustaceans. They live on river bottoms and are a common prey item year-round. Because these prey items are always in the water, you can always use them. Here are a few of the best scud and sowbug patterns for trout.


Bead Body Scud

Bead Body ScudThis scud pattern incorporates a mid-body bead to enhance both sink rate and subtle attraction flash, making it an ideal choice for still water applications where you aim to swiftly reach the desired depth in the water column and employ a slow retrieve.\

  • Imitates: Scuds
  • Typical Size: 12-14
  • Variations: Beaded shrimp, color and size variations

Czech Mate

Czech Mate NymphA compact scud pattern that fishes well in fast riffle water. Bright colors can also look like roe, and muted colors also resemble caddis nymphs.

  • Imitates: Scuds, fish eggs
  • Typical Size: 12-16
  • Variations: Can be tied in green, cream, red and other colors

Killer Bug

Killer BugThis storied fly was developed by the famed Frank Sawyer to help control grayling numbers on the River Avon. For trout, stick to smaller Killer Bugs– the larger sizes are better for bigger fish like salmon. This is an incredibly easy fly to tie– all you need is wool, thread, and copper wire.

The Best Streamers for Trout Fishing

The largest wet flies are streamer patterns. Streamers can be very appealing to larger trout and can mimic a number of creatures. There are a number of streamers that don’t mimic anything in particular– attractor patterns often work well as flies of this size.


Black-Nosed Dace

Black Nose DaceThis simple, effective streamer is great because it mimics many small baitfish. It’s a generic minnow or dace pattern, so it never looks out of place in the water.

  • Imitates: Minnows, dace
  • Typical Size: 2/0-10
  • Variations: Mickey Finn, Little Rainbow Trout

Clouser Deep Minnow

Clousers Deep MinnowThis is a larger pattern– so much so that “to clouser” your rod means to lose control over the tip because you weren’t expecting such a heavy fly. An unusual, brightly-colored fly, these streamers are best for large trout and behave more like jigs than other types of flies.

  • Imitates: Attractor, nonspecific baitfish.
  • Typical Size: 2/0-10
  • Variations: Freshwater Clouser

Marabou Leech

Marabou LeechThe fluffy feathers of the marabou leech give it great movement underwater, helping it mimic plenty of soft-bodied snacks that trout can’t resist. Smaller sizes are better for trout.

  • Imitates: Leeches and annelids
  • Typical Size: 10-4
  • Variations: Bunny leech; many color variations

Muddler Minnow

Muddler MinnowDesigned originally for brook trout, the Muddler Minnow doesn’t mimic a specific type of baitfish; rather, its mottled appearance and movement mimic a number of terrestrial and aquatic prey items.

  • Imitates: Minnows, sculpins, crayfish, large insects
  • Typical Size: 2-12, up to 3x-4x long
  • Variations: Various colors

Choosing Flies For Any Situation

When choosing the best wet flies for trout, it’s never a one-size-fits-all scenario. Flies that perform well during one season might not perform as well in the next. Fish might be biting in one part of the stream and ignoring your flies in another part. You have several things to consider when choosing a fly for the situation.


Depth Matters

Where you put the fly in the water column is important. While dry flies stay on the surface, wet flies can go to the bottom, stay near the top, or hang anywhere in between. In some situations, you may need to get your fly down to where the trout are holding, especially in fast-flowing or deep waters. Other times, you want your fly to stay in the mid-water column or even near the surface. It all depends on where the fish are willing to bite.


Heavy vs. Light Flies

When you need to get deep quickly, using heavy flies is essential. These flies, like bead-head nymphs and streamers, are typically weighted with materials like tungsten beads, and they sink rapidly. Choose heavier flies when fishing in deeper pools or during fast currents. Choose lighter flies when you’re in still waters or want less movement.


Smaller vs. Larger Flies

Smaller wet flies, even if they are lightweight, can still sink relatively quickly due to their streamlined design. These are excellent choices when you need to reach specific depths without the extra weight. They work well for imitating smaller aquatic insects or when trout are feeding near the surface. If the trout are feeding mid-water or towards the bottom, larger flies may be more tempting.


Emergers and Non-Weighted Flies

Emerger patterns or non-weighted flies are designed to mimic insects rising from the depths to the surface. These can be fished in the mid-water column effectively. They provide a more natural presentation for trout suspended in the water column or actively feeding near the surface. Use these flies when you don’t want to get all the way down to the bottom, or as a tailing fly behind a fly that is sitting on the bottom.


Size Selection

Matching the hatch isn’t just about what species of insects are present; you also must pay attention to the size of the insects being eaten. When trout are feeding on smaller insects like midges or mayflies, opt for smaller wet flies. Conversely, when larger insects or baitfish are prevalent, go for larger patterns.

It’s also a good idea to carry a variety of sizes in your fly box. This allows you to adapt to changing conditions and insect activity throughout the day. Sometimes, trout may switch their preference from small to large insects, or vice versa, as the day progresses.


Color Selection

Choosing the right color for your wet fly can make a significant difference. Natural colors like olive, brown, and black often imitate real insects and can be effective in most situations. However, in some cases, using more attractive, flashy colors like chartreuse or orange can trigger aggressive strikes, especially in murky water or low light conditions.

Don’t be afraid to experiment with different colors to see what the trout are responding to on a given day. Observing the behavior of the fish and the prevalent forage can help you determine the most suitable color patterns.

Selecting the best wet fly for trout involves a combination of factors such as depth, size, what’s hatching, and color. Being able to adapt to changing conditions and reading the water and trout behavior will ultimately lead to more success on the river. Remember that while these principles provide a solid foundation, local knowledge and experience can often be the best guide for fly selection in specific fishing locations. Ask around at local fly shops to see what the fish are hitting and what the hatch is like.
