If someone says fly fishing is easy, let them use a grasshopper fly in the middle of winter. While a grasshopper might be a tasty treat for a summer trout, it wouldn’t stand a chance against the frosted breath of a fish in February! Kidding aside, this highlights the crucial and often underestimated skill of fly selection in the art of fly fishing. 

This guide will help you master the art of fly selection and understand what type of fly to use in different fishing conditions. Should you use a wooly bugger for topwater fishing? Or would a dry fly be the better choice? Discover the answers right below.

Understanding the Different Types of Fly Fishing Flies

There are three main types of flies that fly fishers use: aquatic, terrestrial, and dry. Aquatic flies often imitate insects that live in the water. Terrestrial flies mimic land insects that might fall onto the water’s surface (a.k.a. topwater). Dry flies imitate insects that have hatched and are struggling on the water’s surface.

Aquatic flies are then split into three categories based on the life stage of insects: nymphs, emergers, and streamers. 

Nymphs: Nymph flies mimic the immature stages of aquatic insects such as mayflies, stoneflies, or caddisflies. They typically have a streamlined body with gills and leg casings, resembling natural nymphs living on the bottom of the stream or riverbed. 

Emerger: As nymphs become adults, they typically struggle on the water’s surface due to their developing wings. Emerger flies feature a nymph-like body with emerging wings, mimicking a vulnerable stage for insects that fishes usually target.

Streamer: Streamers are elongated flies that imitate baitfish or larger aquatic insects like leeches. They copy the movements of prey that fish actively hunt by sinking and swimming just below the water. A popular example of a streamer fly is the wooly bugger. Wooly buggers come in various colors and sizes, but they generally have a long marabou head and a bead head.

Next are the two types of topwater flies: Terrestrial and Dry. 

Both terrestrial and dry flies entice fish to feed on the water’s surface. Terrestrial flies imitate land insects like grasshoppers or ants that might have fallen in. Dry flies, on the other hand, mimic adult aquatic insects like mayflies or caddisflies that have just hatched and are floating on the surface. 

Matching the Hatch: Understanding What Fish Eat

Matching the Hatch is a crucial concept in fly selection. It means choosing flies that resemble the insects fish are actively feeding on at that specific time. Here are some tips to determine which fly you should use:

Observe the Water: Monitor the water’s surface for rising fish. This behavior often means they’re feeding on emerging insects. Use an emerger fly.

Examine the Bank: Check the banks and surrounding vegetation for recently emerged insects like mayflies or caddisflies. Once you spot them, consider using a dry fly.

Utilize Hatch Charts: Hatch charts contain a list of insects likely to be hatching on a specific body of water. Identify these spots and use a nymph fly.

Beyond the Basics: Additional Factors for Fly Selection

While understanding the hatch is crucial, other factors can influence your fly selection for specific fishing conditions. Consider checking:

• Water Clarity: Opt for smaller, natural-looking flies in clear water. Use muted colors and subtle profiles in pressured waters.
• Fish Size: Match the fly size to your target fish. Try to start with a smaller fly and work your way up from there.
• Current Speed: Use heavier flies such as weighted nymphs and streamers for fast currents. For slow currents, use lighter flies with a smaller profile, such as dry flies and small nymphs.

Consider packing various fly types, sizes, and colors to maximize your fly fishing success. Always observe the water for clues, and don’t be afraid to experiment with different flies until you find what works. You may also want to track what works to refine your approach. Lastly, practice your casting to ensure flies land gently and realistically.

Mastering Fly Selection

There is no single way to master fly fishing. Experiment with different types, observe the water and seek advice from experienced anglers. Once you’re more familiar with choosing the right flies, you may want to experiment with your fly rods to see which suits your fly fishing technique best.
