The Wonder Winged Dun or Spinner is a generic representation for members of the “Leptophlebiidae” (Lepto) family of Mayflies and in particular the various Highland Duns & Spinners, which are members of the “Oniscigastridae” genus. Hatches generally occurs between the months of October and March.

If you have a look at Lepto Duns there are fundamentals of shape and form that are common and are captured by this pattern. Lepto duns occur in a range of colours including olive through to brown, charcoal and grays and shades of ginger, red and burgundy.

This wonder wing concept is accredited to Sydney dentist Dick Deakin and can also be applied to the wonder tail.

Materials

Process

A	Wind the thread in touching turns to the bend of the hook. Understanding hooks If your going to tie in a split tail a good idea is to leave a long tag end of the thread so that you can bring the up between your tail hackle fibres to keep the two sides of the tail separate.

B	Tie in a tail of long hackle fibres so that it finishes about 1.5 times as long as the hook shank. I have tied 4 hackle fibres in here so that each side of the tail when separated will have 2 hackle fibres. Separate the hackle evenly and carefully bring the tag end of thread that you left in step 'A' up between the fibres so as to separate them. Lock the tag end of the thread into place along the rear half of the hook shank.

C	Build up a cigar shaped body of thread on the rear 2/3 of the hook shank.

D	Select a flat black hackle with barbules that are at least twice as long as the gape of the hook. Dry fly hackles Strip the barbules of one complete side of the hackle and from both sides of the butt end. Tie the butt end of the hackle in along the top of the hook with the stripped side laying flat along the top of the hook shank.

E	Whilst holding the hackle with your left hand take the hackle fibres on the bottom part of the hackle and pull the tips of them down toward the shank of the hook. Make the wing smaller rather than larger because the larger the wing the more tendency there is for the fly to spin when casting. When your satisfied that you have them in the correct position take a couple of firm wraps of thread to lock them into place.

F	Tie the front hackle in directly in front of the wonder wing. Wind the hackle forward in touching turns stopping just short of the eye of the hook, tie it off and trim the butt end. Build up a neat head. Neat thread heads Whip finish and varnish the head.
