Knowing these three common hatches for river fishing is the difference between success and failure.
Depending on the time of year, trout (and other angler fish) are eager to take advantage of major insect outbreaks, and this turns into an advantage for the angler. Once humans got the hang of it, especially fly fisherman, we started to see how we could enjoy it too.
Even the pickiest fish will make a move when bigger, meatier offerings come along, and fishing with flies that mimic these insects in their various life stages will definitely improve your odds.
But the main thing is that trout remains a capricious fish, especially when it comes to river fishing. Sometimes the more subtle differences can turn things around in your favor, but they can just as easily make hard fishing even harder.
For serious anglers, finding and identifying insect species that hatch and emerge, and then associating them as an offering, can be both fruitful in the moment and add a feather in the hat of your fishing know-how. .
Most of what we will cover relates to fly fishing for trout, but that is not to say that some of these same facts and principles can be used to target other species. As long as they are known to eat bugs, fish will become active and easier to catch when you pay attention to these three hatches.
One thing to note: this is not meant to tell you what time of year these hatches will occur, as it depends on the region, weather, water temperature, etc. We’ll give you the big traps to watch out for, but it’s up to you when they happen where you intend to fish.
Considering the caddisfly is such an important target species for fish, not to mention its importance as a harbinger of a clean water system, it sometimes seems underestimated in its importance as bait for fish. catch trout. Imitation Caddis now get their fair share of time at the end of the tippet, and for good reason.
The adult caddisfly resembles a moth, but unlike moths, caddisflies spend most of their lives living in water as larvae. Caddisfly larvae typically live in a type of crate they construct from gravel, sand, and plant matter, using their own silk to hold it all together.
In the book Caddisflies: A guide to eastern species for anglers and other naturalists by Thomas Ames, Jr., the author clarifies caddis as being divided into three families: primitive, fixed-retirement, and tube makers. It just means that trout and other fish all target them in these different ways.
One of the best parts of caddisfly is that it can be used as an imitation throughout its various stages, starting with the imitation larvae, then pupa, and finally the adult stage. They can be caught using nymphs, wet flies and dry flies depending on their stage of emergence.
Caddisflies can catch trout throughout their lives from the time they hatch from the egg, emerge, become adults, and even after they die.
Stoneflies are less prolific than mayflies and caddisflies, but due to their size they are welcome food all year round. Trout, smallmouth bass, and many species of sunfish depend on the large nymphs that appear in most waterways across the United States. They are another indicator of clean water, so much so that they cannot even survive in polluted ecosystems.
Catching a fly trap and matching your flies perfectly can be one of the best fishing events of the season.
Stoneflies are the largest of the three main trout stream insects, and when used as a pupa mimic at the right time, they can catch fish when nothing else works. Stonefly nymphs typically live at the bottom of streams, crawling over and around debris to find food and shelter from their many predators.
Fishing for stone fly nymphs is considered one of the best ways to produce catches, especially in early spring, as well as larger fish due to the size of the bait. The nymphs that migrate to shore in the spring to molt into adults are vulnerable to attack by fish, making this an advantageous effort.
Six weight rods, sinking lines and light tips provide excellent trout fishing action with stone fly nymphs. The combination will more quickly lower your offering to the desired level in the water column and keep it there.
Mayflies are so common in streams across the North American continent and are vital food sources for many trout and other anglerfish. Mayflies may seem inconspicuous, but they hatch in droves and can really roll out the trout buffet.
Mayflies can mature, mate, and die on the same day, making them one of the most unique insects on Earth. They live most of their lives as nymphs, emerge as duns and soon after transform into the spinners we all know and love to emulate.
For fly anglers we mostly like to offer fish nymphs during this stage, but there are several models to choose from: the subsurface version that tries to get out of the water, on the surface while they are molting or as as duns about to take flight, during their egg-drop experience, and when they are exhausted and dying.
They come in several categories that fly on many levels like calling swimmers, clingers, burrowers, crawlers, and emergents. The pheasant tail fly is a proven pattern for swimmers, the mars brown is known as a clinger pattern, the hare’s ear is effective for caterpillars, and the popular soft hackle series is ideal for emergent hatching .
Match the hatches…
What is a hatched chart? Simply put, a hatch chart shows approximate seasonal outbreaks for a specific group of insects in a general geographic region. These usually include the fly’s common name (and sometimes Latin name), suggested fly size, recommended fly (such as nymph or dun), and the month or months it hatches or emerges.
Hatch charts can help the potential angler choose the appropriate flies and tackle they are likely to need for a fly fishing trip in certain locations. The angler can then be sure that he has the right flies for a specific trap, or if he is tying flies himself, he can find the list of patterns for those flies in question and create his own.
Get your hands on a hatch chart for the waters you want to fish and put the information we’ve shared to good use.
Aquatic insects as bait
The endless supply of fly patterns is vast and growing, but as fly anglers well know there is always room in the fly box for another food source pattern that will catch a game fish. .
The life cycle of these insects helps determine whether we practice dry fly fishing, nymphing, or another approach. Pay close attention to the most common hatches, learn about the flies that translate to insect life stage, and you’re set for a better all-around experience.
