Simplified: Flies
The truth is, fly fishing isn’t complicated — it can just look that way. Simplified Fly Fishing is built on one idea: if you understand the basics, everything else gets easier. This series walks through the core pieces of fly fishing, stripping away the fluff and focusing on what actually matters. Whether you’re brand new or looking to refresh what you know, consider this your no-nonsense guide to fly fishing, Wooly Buggin’ style.
Simplified: Flies
Flies are lightweight lures designed to imitate what fish eat — from insects and baitfish to crustaceans and beyond. They’re made from natural and synthetic materials that create lifelike movement and come in a few main types: dry flies, which float on the surface; nymphs, which drift below; and streamers, which imitate larger prey. Other effective styles like wet flies, poppers, and terrestrials round out the list. With just a handful of proven patterns, you can catch trout, bass, and bluegill almost anywhere — no need to overthink it.
What Are Flies?
Flies are near-weightless lures that are designed to mimic the things fish eat. They’re too light to cast on a conventional setup, which is why we use a fly rod — the line does the work of carrying the fly through the air.
Flies can imitate just about anything a fish might consider food- from insects and baitfish to crustaceans and mice. Whatever we’re using, our goal as fly anglers is to make our flies look and move like the real thing.
Walk into any fly shop and you’ll see hundreds of patterns, each meant to look like a different kind of prey. Or a different size/shade/tone of the same prey, but we’ll get to that later.
Some flies are “realistic” imitations of natural forage, meant to mimic the real thing. Others are “impressionistic” flies that look like a whole range of natural forage, but not a singular item of prey. These flies don’t look like anything in particular, but somehow look like a whole bunch of things at the same time.
The best example of an impressionistic pattern is the good ol’ Wooly Bugger, mimicking anything and everything under the water that fish will chow down on. It doesn’t look like anything, but at the same time looks like everything.
We’ll get into more detail about what those flies represent later, but for now, just think of a fly as a small, lightweight imitation of something a fish might want to eat.
What Are Fly Fishing Flies Made Of?
Flies can be made from just about anything that helps them look and move like real prey. This can literally be anything, feathers, fur, your dog’s hair, yarn, goodies from the arts and craft store- the list is endless. If it can be tied on a hook, I’m sure someone’s tried to make a fly out of it.
Traditionally, flies are tied using natural materials- stuff like bird feathers, animal fur, and bits of hair that add movement or profile. These days, you’ll also find a boatload of synthetic materials in the mix to compliment the natural stuff. Flashy fibers, rubber legs, and plastics all help create action, shine, and the right profile to fool fish.
Light weights (like small beads, lead wire, or cone heads) can be added to help a fly sink to the right depth. Whether you’re trying to keep it floating high on the surface or get it down deep fast, the materials and weight are what make that possible.
There’s always been some debate about what counts as a “real” fly, especially with how creative people have gotten in recent years. Some anglers think a fly tied with too much synthetic stuff doesn’t count as a true “fly” and will scoff at those using them.
For all I care, if you can throw it on a fly rod and it gets fish to bite, it’s a fly.
Common Natural Fly Materials
Natural materials have been used in fly tying for centuries. Here are a few of the most common used to make fishing flies:
- Feathers: From birds like roosters, pheasants, ducks, and turkeys
- Fur: Rabbit, squirrel, and fox fur add a “buggy” element to flies.
- Bucktail: Used to make tails and bodies in many baitfish patterns.
- Hair: Deer, elk, and moose hair are used for buoyant bodies and wings (like in dry flies).
- Marabou: Soft, flowing feather fibers that add movement- often used in streamers.
Common Synthetic Fly Materials
Synthetic materials have exploded in popularity, offering brighter colors, more durability, and new ways to create movement in the water. This short list doesn’t even come close to all the options out there.
- Flash and Tinsel: Adds sparkle and visibility to attract fish.
- Rubber Legs: Create lifelike twitch and pulse in the water.
- Foam: Keeps flies floating high and adds shape to poppers or terrestrials.
- EP Fibers / Craft Fur: Lightweight, durable materials for baitfish patterns.
- UV Resins: Used to coat and harden flies, adding durability and shine.
What Are the Different Types of Flies?
Flies come in a huge variety of shapes, sizes, and styles. Most of them fall into three main categories: dry flies, nymphs, and streamers. Each one imitates a different type of prey or a specific stage in a prey’s life cycle.
Dry flies float on the surface, nymphs drift below it, and streamers swim through the water like small fish or other moving food.
Beyond those main categories, there are other styles of flies that don’t fit perfectly into one box — like wet flies and poppers — but they all follow the same basic idea: imitate something alive and make a fish want to eat it.
Dry Flies
Dry flies are flies that float on top of the water that imitate an adult or expired insect. If you think of the classic image of a fly angler casting a line, there’s a good chance you’re picturing a dry fly at the end of it. These flies imitate adult insects that have hatched and are sitting on the surface — things like mayflies, caddisflies, stoneflies, or midges.
Dry flies are most effective when fish are actively feeding on or near the surface. They are extremely fun to fish when the time is right, but not as productive when there’s no “hatch” going on.
Common dry fly patterns include the Adams, Elk Hair Caddis, Parachute Adams, and Royal Wulff — all simple, proven flies that catch fish just about anywhere.
Nymphs
Nymphs imitate insects that haven’t fully matured yet. They’re the underwater stage of flies like mayflies, midges, and caddisflies. These bugs live below the surface for most of their lives, spending a couple years growing underwater before they are ready to hatch and come to the surface
You’ll often hear that a trout’s diet is 60% to 90% (depending on who’s talking) subsurface. This is why using nymphs is so effective. Most of the time, trout are feeding on little tiny nymphs since they are most abundant in most bodies of water. Plus, it’s easier for them to slurp down as they drift through the current.
Nymphs are fished under the surface near the bottom, usually with the help of an indicator (a fancy word for “bobber”) that lets you see subtle eats. The goal is to let your fly drift naturally with the current, just like a real insect tumbling along the streambed. You’ll start to dream about bobbers ticking along the bottom and plummet down as the fish eats.
Some of the most reliable nymph patterns include the Pheasant Tail, Hare’s Ear, and Zebra Midge — all simple, versatile flies that work in nearly any water.
Streamers
Streamers are larger flies that imitate bigger prey like baitfish, leeches, or crustaceans. They can range from an inch long to over a foot (for species like musky), but in general, they’re much bigger than dry flies or nymphs. They’re meant to target fish chowing down on heartier meals.
Unlike nymphs or dry flies when you drift them along the current, streamers are mostly fished actively. You’ll retrieve them with short line strips or pulses of the rod tip to mimic injured or fleeing prey. They don’t always trigger bites out of hunger; sometimes it’s pure instinct or aggression. Those reaction strikes are what make streamer fishing so exciting — it’s visual, aggressive, and incredibly addicting. It’s my favorite way to fish.
A couple classic and reliable streamer patterns include the Wooly Bugger and Clouser Minnow- both proven flies that consistently move fish. The list of streamer flies, especially with modern techniques, has grown longer than a CVS receipt. But they’re all trying to do the same thing- catch aggressively feeding fish on the hunt for a chunky meal.
Other Types of Flies
Dry flies, nymphs, and streamers make up the three big buckets of fly fishing flies, but there are plenty of other patterns that can be just as effective.
These flies often target specific situations or types of fish that don’t fit quite as neatly into the main categories.
Terrestrials
Terrestrials imitate land-based insects that fall or get blown into the water. Things like ants, beetles, grasshoppers, and crickets. They’re especially effective during the summer when these bugs are most active. A big foam hopper twitching across the surface can draw explosive takes from trout and bass alike.
Wet Flies
Wet flies are sort of the middle ground between dry flies and nymphs. They’re fished just under the surface and imitate drowned insects or bugs that are emerging toward the top. Wet flies have been around forever, and they still flat-out catch fish.
Poppers
Poppers are surface flies designed to create a commotion at the top of the water column. They have buoyant heads — usually made of foam, hair, or cork — that create a “pop” when stripped through the water.
Poppers are a blast to fish and are most often used for warmwater species like bass, panfish, and even pike.
Best Fishing Flies for Beginners
There are thousands of fly patterns out there, but you don’t need every fly from the shop to catch fish.
A small handful of proven patterns will cover just about any situation you’ll run into, especially if you’re fishing warmwater species like trout, bass, and bluegill. Here are a few reliable flies to get you started:
Best Flies for Trout
Dry Flies for Trout
- Elk Hair Caddis: Floats high, easy to see, and imitates tons of natural insects.
- Adams: A versatile, all-purpose dry fly that works almost anywhere. Some anglers say a size 16 Adams fly is all you need to imitate any fly out there.
Nymphs for Trout
- Pheasant Tail Nymph: Simple and effective; imitates a wide range of underwater insects. A classic “impressionistic” nymph that looks like any bug floating around.
- Hare’s Ear Nymph: A classic pattern with a tempting “buggy” look to it.
- Zebra Midge: Simple and effective. Imitates the larval stage of midges and catches fish everywhere. Sometimes, I wonder how and why fish eat these things, but they sure as heck do.
Streamers for Trout
- Wooly Bugger: The ultimate all-around streamer; it imitates leeches, baitfish, and more.
- Muddler Minnow: Great for larger trout or when fish want a bigger meal.
Other Flies for Trout
- Terrestrials: Can’t leave home without a handful of hoppers, ants, and beetles. Very productive in the summer months.
Best Flies for Bass
Streamers
- Clouser Minnow: A must-have for smallmouth and largemouth; sinks fast and looks like a real baitfish. Well kind of…
- Deceiver: A classic, long-profile baitfish pattern that’s great for larger bass.
- Wooly Bugger: Yep, it works for bass too. Swim it, jig it, or strip it — bass love it. My go-to for pretty much any species out there.
Poppers/Topwater
- Boogle Bugs: Classic topwater popper that brings bass to the surface. Watch them slurp it down.
- Mr. Wiggly: More subtle topwater pattern for finicky fish wanting to sip food off the surface.
- Gurglers: Another classic popper pattern with a unique “gurgling” action at the surface.
Best Flies for Bluegill
- Wooly Bugger: Well, obviously. Throw smaller Buggers for bluegill and have a day.
- Bead Head Nymphs: Small, weighted flies that sink slowly and catch bluegill all day. Don’t get too picky with what type of nymph- bluegill will hammer pretty much anything.
- Small Poppers: Few things are more fun than watching a bluegill smack a popper.
Conclusion
Flies don’t have to be complicated. At their core, they’re just small imitations of what fish eat — and knowing the basic types is all you need to start getting bit.
Whether you’re throwing dry flies to rising trout, stripping streamers for bass, or watching bluegill sip a foam spider off the surface, the idea is the same: make your fly look like food and put it where the fish are. The rest comes with time, practice, and a little trial and error.
Keep it simple, stay curious, and have fun with it — that’s what Simplified Fly Fishing is all about.
