Midge Flies for January Fly Fishing

mercury midge fly

1. Mercury Midge

Don't make the mistake of thinking that winter fishing is a lost cause. The water might be cold with frost and ice around, and the trout might be on a diet, but the reality is they never stop eating or biting. Their metabolism indeed slows down in the colder months, but you still have good chances with the right fly.

The Mercury Midge is a larvae fly that imitates the early stages of midge development. It's typically made using thread and glass on a hook and is particularly effective in the winter months. The Mercury Midge gets its name principally from the glass bead at the head. This mimics an air bubble produced by the thorax of a midge close to the surface.

Since Midges account for around 50% of a trout's overall diet, the Mercury Midge fly is a successful option. Like other insects and animals, midges are less productive in the winter, but they are still present in the riverbed and surrounding vegetation. The clear glass on the Mercury Midge is an irresistible option for a hungry trout in winter rivers.

Disco Midge - Best Fly For Nymphing in January

2. Disco Midge 

The most popular form of winter food for trout is by far midges, predominantly in larvae form. Midge larvae are worm-like in appearance. They have slender curved bodies with segmented abdomens. They also have small heads with a clear bubble-like appearance on the water. In winter, the water can be dark and muddy, when a Disco Midge is most effective.

A Disco Midge is designed to imitate a midge larva floating at the surface of a winter river or lake. The bright thread and clear bauble on top are bright enough to catch the trout's attention in the muddy waters, but it won't scare them away by being too flashy.

It's quite common for the rivers and lakes to get cloudy and muddy in the winter months as the silt at the bottom turns over. A conventional midge fly might still be useful in such conditions, but the disco midge gives you that extra attention-grabbing feature to draw the trout's eye. If your fly isn't sufficient and you notice muddy conditions, try the disco midge.

Rainbow Warrior

3. Rainbow Warrior 

It's not always easy to tell what your angling conditions will be like lakeside in the winter. You might find the water is clearer than expected due to runoff and floods. Other times it might be dark brown and impenetrable. For best results, it's advisable to carry a selection of midge flies, but one that should always be in your box is the Rainbow Warrior.  

Tied to look like a midge larva, the Rainbow Warrior is the ideal pattern for many water conditions. The multicolored body and spiky mane not only convinces the winter trout that it's the real deal, but it also catches their eyes in murky rivers and lakes without standing out. The Rainbow Warrior fly delivers excellent results and is a must in the winter anglers flybox.

If you want a winter pattern that's simple yet effective and that stands out in muddy water without being too flashy, the Rainbow Warrior Midge is the one to choose. With a Rainbow Warrior Midge, you can virtually guarantee a bite – the hungry trout can't resist the sight of this tasty looking fly.

Juju Bee Fly Fishing Fly

4. Juju Bee Midge

When other aquatic insects are dormant and inactive during the winter months, trout seize the opportunity of snagging anything that looks edible floating in the substrates. This often means midge larvae that have come loose from their tunnels or shelters in the silt or vegetation and drift along the water's surface.

Opportunistic trout often jump at the chance of an easy meal making this time of year especially fruitful for anglers with midge patterns. That said, occasionally, the trout so become fussy or wise to an obvious meal. For times like this, you need a fly that's a little more covert and discreet.

The Juju Bee Midge is the ideal solution. This fly pattern is instrumental in rivers in the winter months as it combines colorful threads with realistic-looking feathers. The midge is made to look like the midge larvae or adult midge floating downstream.

Kaufman Stone

6. Kaufman Stone

The conventional wisdom for winter fishing was always to fish big, black, and deep. This is partly due to the trout's situation, hiding in the murky depths of cold rivers and lakes, but also because of the food source availability at this time of year. Often trout will look out for water beetles floating by in the barren depths.

Water beetles are fat black insects that can be found in rivers and lakes around the world. They are a prominent food source for trout in the winter months and can be effectively replicated by the Kaufman Stone Nymph. The Kaufman Stone Nymph is big, black, and deep. It sinks to the level of the trout and easily imitates a water beetle in addition to the stone fly.

This pattern is handy in the winter months as it appeals to trout on two counts.

It further appeals to the trout because of its depth and shape, making it a hard to resist morsel.

Streamer Fly Patterns for January

Autom Splendor

12. Autumn Splendor

It's best for winter fishing to use streamers in the afternoon when the trout are likely to be closer to the surface. As the name suggests, the Autumn Splendor is more useful when trout are more mobile. However, that doesn't mean this active form of angling can't be successful in the winter months.

The Autumn Splendor is a classic tie form that is designed to imitate surface bugs and flies.
