# **How to Choose Dry Trout Fishing Flies: 12 Black Spider, Knotted Midge, Black Gnat, 12/14/16**
When it comes to dry fly fishing for trout, selecting the right fly can make the difference between a successful day on the water and going home empty-handed. Among the most effective dry flies for trout are the **Black Spider (Size 12)**, **Knotted Midge**, and **Black Gnat (Sizes 12, 14, 16)**. These flies imitate various natural insects that trout feed on, making them essential additions to any angler’s fly box.
In this guide, we’ll break down why these flies work so well, when to use them, and how to choose the right size for different fishing conditions. Whether you’re a beginner or an experienced angler, understanding these patterns will help you catch more trout.
## **1. Black Spider (Size 12) – The Versatile Attractor**
The **Black Spider** is a classic wet fly that can also be fished as a dry fly with the right technique. Its sparse, soft-hackle design creates subtle movement in the water, mimicking emerging insects or small terrestrials.
### **Why It Works:**
– **Imitates Multiple Insects**: The Black Spider can resemble midges, small caddis, or even tiny stoneflies, depending on how it’s presented.
– **Great for Slow Water & Riffles**: Its buoyant design allows it to float well in calm pools, while the hackle helps it stay visible in faster currents.
– **Effective in Low Light**: The dark silhouette stands out at dawn, dusk, or on overcast days when trout are actively feeding.
### **When to Use It:**
– Early morning or late evening hatches
– When trout are keying in on small, dark insects
– As a searching pattern when no specific hatch is occurring
## **2. Knotted Midge – The Tiny but Deadly Pattern**
Midges are a year-round food source for trout, and the **Knotted Midge** is an excellent imitation of these tiny insects. Typically tied in sizes 18-22, a slightly larger version (such as a **Size 16**) can be effective when trout are selectively feeding on midge clusters.
### **Why It Works:**
– **Ultra-Realistic Profile**: The segmented body and sparse hackle closely resemble midge pupae or adults.
– **Works in Cold Water**: Midges hatch even in winter, making this fly a must-have for year-round fishing.
– **Pairs Well with a Dry-Dropper Rig**: Use it as a trailing fly below a larger dry fly for double the chances.
### **When to Use It:**
– During midge hatches (common in tailwaters and spring creeks)
– In slow-moving or still water where midges thrive
– As a subtle option when trout are being picky
## **3. Black Gnat (Sizes 12, 14, 16) – The Classic Dry Fly**
The **Black Gnat** is a timeless dry fly that imitates small dark mayflies, gnats, and even beetles. Its simplicity and effectiveness have made it a favorite among anglers for generations.
### **Why It Works:**
– **Matches Multiple Insects**: Trout often mistake it for small mayflies, midges, or even terrestrials like ants.
– **Highly Visible on the Water**: The dark body contrasts well against the surface, making it easy for anglers to track.
– **Works in Various Conditions**: Effective in both fast and slow water, especially during summer hatches.
### **When to Use It:**
– On overcast days when dark flies stand out
– During summer when small dark mayflies (e.g., Blue-Winged Olives) are hatching
– As a prospecting fly in areas with mixed insect activity
## **Choosing the Right Size (12, 14, 16)**
Fly size matters—trout can be selective, especially in clear water. Here’s a quick guide:
– **Size 12**: Best for faster water or when trout are aggressive. Works well as an attractor.
– **Size 14**: A balanced choice for most conditions, imitating medium-sized insects.
– **Size 16**: Ideal for picky trout in slow, clear water where subtlety is key.
## **Final Tips for Success**
– **Observe the Hatch**: Match your fly size and color to the insects trout are feeding on.
– **Adjust Your Tippet**: Use lighter tippets (5X-7X) for smaller flies to ensure a natural drift.
– **Experiment with Drifts**: Try dead-drifts, slight twitches, or skating the fly to trigger strikes.
By adding the **Black Spider (12)**, **Knotted Midge**, and **Black Gnat (12/14/16)** to your fly box, you’ll be prepared for a wide range of trout fishing scenarios. These flies have stood the test of time—trust them, and you’ll hook more fish.
