When you think of fly fishing, two things come to mind – the casting of a fly line and the fly on the end of the line. Fly fishing flies are a unique aspect of our sport and are without doubt the most hotly debated aspect of fly fishing. Flies, typically fall into 4 categories, nymphs, dry flies, streamers and wet flies. Each of these types of flies have hundreds of variants that work in different situations, it would take an age to describe them all. So what we’ll focus on understanding is the key differences between the different types of flies.
Nymphs are a subsurface fly; they can be classed as either ‘nymphs’ or ‘lavae’ – they key difference between these two are that nymphs look a bit like the fly they will hatch into whereas larvae don’t. Trout feed on nymphs as they float downstream or up to the waters surface. The nymphs we tie onto our fly line imitate nymphs that are floating down stream after being dislodged by water pressure, a nymph that is moving to another food source or a nymph that is floating to the surface in order to hatch into a fly.
Fish feed heavily on nymphs, a trout, for example, can sit in on the bottom of a river and simply move toward the floating nymph, open its mouth and suck the nymph down. It’s easy food for little effort – that’s why fly fishing with nymphs can be so successful.
Dry Flies
A ‘dry fly’ is simply a nymph that has hatched into an insect with wings that sits on top of the water, or flies above it. The most common time for nymphs to hatch into flies, is during the warmer months. It is common to have a large hatch of flies on a summers evening, fish will feed aggressively at these times to chomp down as many flying insects as possible – this is the best time to fish with a dry fly. You’ll increase your chances of hooking ‘rising’ fish, if you ‘match the hatch’, or match the type of dry fly you use to the type of insects hatching on the water.
Streamers are completely different to the two above types of flies. They are fished under water and represent a small batfish. Streamers are typically longer, larger flies that appear bushier; some streamers use bright materials which will often attract a hungry fish. Streamers are fished near the bottom of a lake or river. They are cast out, allowed to sink then retrieved; you’ll get some very aggressive bites or takes on a retrieved streamer as the chasing trout swims in and hits the fly by surprise.
Streamers are also a popular choice for fly fishing at night time.
Wet Flies
These flies, as you’d expect (and similarly to streamers) are fished in the water. Wet flies represent either small fish or larger swimming insects. Wet flies are commonly fished with a sinking line or intermediate line and are retrieved as they sink to the bottom of the lake or river.
Wet fly fishing is one of the oldest types of fly fishing and is quickly being overtaken by techniques such as nymph fishing.
The above types of flies cover the majority of all flies sold today. Each type has a huge number of variations or species, it can be quite daunting knowing which ones to choose for which pieces of water. The best way to decide on what fly to choose is to try and understand the aquatic life of the piece of water you’re fishing or even easier talk to someone and ask them what types of flies work well on that piece of water. Most fly fishermen will be happy to help you out if you are trying to learn to fly fish.

Tying up a couple of leaders can save you time on the water. I tie tapered leaders of varying length to ensure that I am completely prepared for all types of water that I may encounter on the trip. Gather each leader I tie in a looped bundle and put them into pockets in my vest, so when the time calls I can pull them out and tie them straight on.
