Tying Davie McPhail's "Goose CDC Iron Blue Dun"

In this week's video, Davie's tying up a twist on the classic Dun pattern using Goose CDC but first, let's have a look at the cycle of the Iron Blue.While the Iron Blue has been heavily affected by abstraction, pollution, and dredging, you'll find that trout love eating these little flies.All upwinged flies go through four unique stages in their lifetime: egg, nymph, dun, and spinner. The opening stages are spent underwater whereas the latter are the two winged stages. 

Skipping the egg stage, the nymph is the first stage post-hatching. Nymphs have three tails and mainly feed on algae and rotting vegetation. Nymphs are sorted into six categories that describe how they have adapted to their habitat and how they act within it. These are well imitated by a classic Pheasant Tail Nymph.
The Nymphs of our Iron Blue, which is otherwise referred to scientifically as Alainites muticus are what is referred to as "agile darters". As an "agile darter" these creatures are unique and a special interest to anglers due to the way that they quickly swim around the water in search of more food thus Trout can eat them even when there is no hatch of flies.

Imitating the nymph's natural darting movement is important when it comes to moving your fly around the water. A tip to achieve short, jerky movements for your nymph would be to dip the rod tip just below the water.

Now in the form of a Dun, the Iron Blue is a tiny fly when compared to other popular up-winged flies that are prevalent during the springtime, with its main emergence period of April/May.

Unlike some other flies, the Iron Blue has a second generation that emerges in September/October. The Iron Blue is known for giving good sport no matter the weather conditions right through the season

Davie McPhail ties an Iron Blue Dun this week with Goose CDC, which results in a high-quality fly.
