# **How to Choose the Best Colorado Caddis Nymph Flies in Sizes 14, 16, and 18**
When it comes to fly fishing in Colorado, caddis nymphs are a must-have in your fly box. These insects are a staple food source for trout, making them highly effective for anglers targeting rivers and streams. If you’re looking for a reliable selection of caddis nymphs, **KyleBooker’s** **12 Colorado Caddis Nymph (One Dozen in Sizes 14, 16, 18)** is an excellent choice. In this guide, we’ll break down how to choose the right flies for different fishing conditions and why this assortment is a game-changer for your fly fishing success.
## **Why Caddis Nymphs Are Essential for Colorado Waters**
Caddisflies (order Trichoptera) are among the most abundant aquatic insects in Colorado rivers. Unlike mayflies, which have a more distinct emergence cycle, caddis nymphs are active year-round, making them a consistent food source for trout. Their larvae crawl along the riverbed, and when they pupate, they drift in the current—creating prime feeding opportunities for fish.
A well-stocked fly box should include caddis nymphs in multiple sizes and weights to match the natural insects in the water. The **KyleBooker 12 Colorado Caddis Nymph assortment** provides a balanced selection in sizes 14, 16, and 18, ensuring you’re prepared for various fishing scenarios.
## **Understanding Fly Sizes: 14, 16, and 18**
Choosing the right fly size is crucial for matching the hatch and fooling selective trout. Here’s a breakdown of when to use each size:
– **Size 14**: Ideal for early-season fishing when caddis larvae are larger. This size works well in faster currents where trout are less picky.
– **Size 16**: A versatile mid-size option that imitates both mature nymphs and emerging pupae. Perfect for summer hatches when trout are actively feeding.
– **Size 18**: Best for clear, slow-moving water or pressured fish that inspect flies closely. Smaller flies can be the key to success in technical fishing situations.
By having all three sizes in your fly box, you can adapt to changing conditions and increase your chances of hooking more fish.

## **When and How to Fish Caddis Nymphs**
To maximize success with these flies, consider the following techniques:
1. **Euro Nymphing**: Use a tight-line approach with a weighted nymph (size 14 or 16) to keep the fly near the bottom.
2. **Indicator Fishing**: In deeper pools, suspend a size 18 nymph under a strike indicator for a natural drift.
3. **Swinging Pupae**: During a caddis hatch, try swinging a size 16 or 18 nymph just below the surface to imitate emerging insects.
