I have been working on this pattern for several days. I’ve tried all manner of body styles, materials, colors, and hooks, and finally boiled it all down to this fly, which I call the Husk Dun. It imitates a Mayfly Dun just after hatching. When a mayfly hatches, it rests on the surface for a moment, drying its wings, while the discarded husk hangs just below. That is what this fly imitates.
It is somewhat of a ‘novelty’ pattern I suppose, unnecessarily detailed but a fun one to tie, and I expect it will be enjoyable to fish with as well. After concluding the Husk dressing, I experimented with various extended body materials for the dun. At first I tried a dubbing extended body. It was very beautiful, but it was extremely time consuming and delicate. I then tried a elk hair one. It was quick, tough, and floated well…..but I just didn’t like the look of it. I then tried a furled yarn body. That clicked, and so the Husk Dun came to be.
You can tie it in any colors you wish, transforming it from a Blue Dun to any other mayfly species. The pupa husk you can color with markers (gasp!) to imitate various nymph types…but I prefer to leave it as it is from the package.
While testing in a aquarium, I found that the little bugger floats just as intended, husk dipping below the surface and the Dun bobbing cheerily above. When fishing, I think it would be good idea to anoint the dun with dry fly dressing, and rub the husk with saliva or creek water. Here are some photographs from testing. I apologise for the over-exposed pictures.
