# **How to Choose McGruber Massacre Nymph Emergers Purple – Premium Trout Fly Fishing Flies**
Fly fishing for trout is an art, and selecting the right fly can make all the difference between a successful day on the water and going home empty-handed. Among the many effective patterns available, the **McGruber Massacre Nymph Emergers Purple** stands out as a premium choice for anglers targeting selective trout. In this guide, we’ll break down why this fly is so effective, how to choose the right size and variation, and the best techniques for fishing it.
## **Why the McGruber Massacre Nymph Emergers Purple Works**
The **McGruber Massacre Nymph Emergers Purple** is designed to imitate emerging mayflies, caddisflies, and other aquatic insects in their transitional stage—when they are most vulnerable and trout feed aggressively. The **purple hue** adds a unique trigger, especially in stained or low-light conditions, where natural colors may be harder to see.
Key features of this fly include:
– **Realistic silhouette** – Mimics the shape of emerging nymphs.
– **High-visibility purple** – Attracts strikes in murky water or when fish are keyed in on subtle movements.
– **Quality materials** – Durable CDC (Cul de Canard) feathers and synthetic fibers ensure lifelike movement.
– **Weighted or unweighted options** – Allows for different presentations depending on water depth and current speed.
## **Choosing the Right Size and Variation**
### **1. Size Selection**
The **McGruber Massacre Nymph Emergers Purple** comes in sizes ranging from **#12 to #20**. The best size depends on the hatch and trout feeding behavior:
– **#12-#14** – Ideal for larger mayfly and caddisfly emergers in faster water.
– **#16-#18** – Perfect for midge and small mayfly hatches in spring creeks and tailwaters.
– **#20 and smaller** – Best for highly pressured trout in clear, slow-moving water.
### **2. Weighted vs. Unweighted**
– **Weighted versions** sink quickly, making them great for deep pools and fast currents.
– **Unweighted or lightly weighted flies** excel in shallow riffles and when fishing the film layer where trout sip emergers.
### **3. Hook Type**
– **Barbless hooks** are preferred for catch-and-release fishing.
– **Scud or curved hooks** enhance the natural drift of the fly.
## **Best Fishing Techniques**
### **1. Dead-Drift Nymphing**
Use a **Euro-nymphing or indicator rig** to present the fly naturally in the current. A **slight twitch** can imitate the struggling motion of an emerging insect.
### **2. Swing Technique**
In slower water, cast across the current and let the fly swing downstream—trout often strike as the fly rises in the water column.
### **3. Dry-Dropper Setup**
Pair the **McGruber Massacre Nymph Emergers Purple** with a dry fly (like a Parachute Adams) as a dropper. This allows you to target both surface-feeding and subsurface trout.
## **When and Where to Use It**
– **Early morning and late evening** – Trout are most active during low-light periods.
– **Stained or off-color water** – The purple stands out better than natural colors.
– **During a hatch** – Match the size to the emerging insects.
## **Final Thoughts**
The **McGruber Massacre Nymph Emergers Purple** is a must-have in any trout angler’s fly box. Its lifelike design, versatility, and high visibility make it a deadly pattern in various conditions. Whether you’re nymphing deep runs or fishing the film, this fly will help you fool even the most selective trout.
