Night fishing for trout is an extreme amount of excitement, but what flies are the best for this? Well I have compiled a list of some of my best night fishing for trout flies. These include several mouse fly patterns and streamer fly patterns that you might not have expected. There are a couple ways to fish all of these patterns and that includes swinging and stripping. When I say swinging and stripping that might sound a little dirty, but you can rest assured this is g rated and costs less than anywhere else that might have stripping taking place. Read to learn more about the best mouse fly patterns and streamerr fly patterns for trout fishing.

Fly Fishing Mouse Patterns at Night
Trout have excellent vision at night. It is actually so good that they can see darker flies better because of the way they silhouette against a dark sky. A light colored fly might have much less contrast and be more difficult for the trout to hone in on. So you will notice the color choices of some of these flies and might otherwise think I was insane, but you can rest easy knowing that these flies are all proven producers of large brown trout and rainbows at night.
Mouse Rat Fly Pattern:
This is a pretty large mouse fly for trout. This seems to be one of my “go to” flies for night fishing large browns. The size of this fly will attract a lot of attention from the fish. It moves quite a bit of water and is sized about perfectly to represent an adult mouse. Notice the heavy monofilament hook guard, this will keep your fly from hooking most trees and logs, but will not really effect your hookup rate on trout (that I have noticed).
The Loco Mouse Pattern:
This is a smaller fly pattern that will often work when many other mouse patterns fail on your night fishing trip. These tend to float lower in the water and their small size will trigger hits from trout that refuse to eat a larger fly. I am not sure if the picky trout are eating it because it is smaller or because it usually sits lower in the water, but either way it works. 
The Morrish Mouse Pattern:
This is certainly near the top of my list of night fly fishing patterns for trout. If I were on my way to the river and realized I had forgotten this pattern I would probably turn around and go back home to get it. This fly had a wide body that moves a ton of water, a nice rabbit strip tail to give it some under water appeal and a bit of foam on top to keep it floating good for hours. The shape of the foam around the head will “pop” and give the monster brown trout something to consider. 
Other Fly Fishing Mouse Patterns Worth Mentioning
Mini Mouse Lure:
This is just a small version of the Standard mouse rat fly, these are worth keeping around when fish get finicky. This fly actually works during the day pretty good. It has the leather tail and ears, along with a monofilament hook guard for snag prevention.
Standard Mouse Fly Pattern for Trout
Just another variation of the Mouse fly, this is an overall pretty good pattern, but personally I like them to be less trimmed than this fly usually. The natural flare of the deer hair really pushes a lot of water and attracts attention from the fish. This fly has its place when the fish are not very feisty and looking for an easy meal. 
Streamer Flies For Trout
Streamers are a good way to hook fish after dark. As mentioned above, I prefer darker flies for the night fishing game. You can coat these streamers with fly floatant and keep them close to the surface, or leave them natural and swing them through pools and holes. However you choose to fish them I am sure you will enjoy the outcome. They are extremely effective flies for night fishing trout and should not be held responsible if a trout pulls your rod out of your hands.
Butt Monkey Streamer Fly
This is one of many variations of dark colored streamers that I have had success with for large brown trout at night. throw your fly strait across the river and don’t mend it. Let the current move the fly, this will have this fly swinging through the big trouts zone and attract aggressive fish. The most enjoyable part about swinging flies in this manner is the strike from the fish. It always comes very suddenly and feels really good! 
Lady Gaga Streamer:
This is just a brown version pretty much of the butt monkey fly above. This is also a good color configuration during the day, as it does a pretty good job of representing crayfish or crawdads. Yes, trout do eat crayfish!
