Burk’s Hunchback Infrequens (HBI)
Tying Instructions
1. Attach the hook to the vise. Add 4-5 wraps of lead-free wire around the thorax region. Leave some space behind the eye of the hook.
2. Attach the thread to the hook behind the eye, leaving a 3 ” tag of thread. Trim off this tag of thread. It will be used for ribbing.
3.Secure the leadfree wire with thread wraps and build a thread base from behind the eye to the tail tie-in position. Keep the thread body even and smooth.
4. Select 8-10 fibers of Woodduck or Imitation Woodduck for the tail. Keep the tips of the tail segment even.
5. Attach the tailing fibers with a couple of wraps and adjust the tail length so that it extends to just below the hook. Then secure with additional wraps.
6. Secure the butt of the tail fibers along the shank with thread wraps to just behind the lead wraps.. Finish the wraps with some acrylic head cement for a shiny surface. This will add to the translucent effect of the fly.
7. Mix a dubbing blend and attach some dubbing blend to the thread at the tail tie-in position. Lock in enough fibers with one wrap that you can twist the dubbing around the thread in a loose manner.
8. Dub a slender, tapered body to just past the midpoint of the hook.
9. Remove the unused dubbing from the thread and secure with some thread wraps.
10. Wrap the thread ribbing forward with even-spaced turns. Secure with a couple of thread wraps.
11. Attach a strip of Turkey tail for a wingcase.
12. Apply dubbing to the thread and interlock the dubbing fibers to the hook shank with one wrap. Wrap a heavy thorax that is about 50% larger than the abdomen.
13. Leave enough room behind the eye to secure the wingcase.
14. Attach 5-6 Woodduck fibers to the near side of the shank in front of the thorax. These represent legs and should extend just past the wingcase. Adjust the length of the fibers so that they do not exceed the length of the thorax. Secure with a couple of tight thread wraps and trim off the butts.
15. Attach another set of 5-6 Woodduck fibers to the far side of the shank in front of the thorax and adjust the length so that the fibers do not exceed the length of the thorax. Apply a couple of tight thread wraps and trim off the butts.
16. Bring the wingcase over the thorax and tie in.
17. Create a head in front of the wingcase and whip finish. A little head cement to the wingcase helps to preserve the fibers.
18. The finished Hunchback Infrequens.

Andy Burk
Burk’s Hunchback Infrequens (HBI)
This fly was originated by Andy Burk for PMD hatches on the Fall River in Northeastern California. Andy worked as a guide and noticed a drop-off on the hits of Pheasant Tail Nymphs. He discovered that the trout became accustomed to the PTN and declined the offering. Part of the problem was translucency and a hunchback configuration. Andy resolved this by selecting a scud-type hook and utilizing a rust-colored rabbit dubbing that matched the nymphs color but also gave a fibrous translucency to the fly.
Baetis Colorations
The fly is used as a primary nymph pattern for PMD’s but can also be used for Baetis hatches. Use of a Scud-type hook is also found on John Barr’s Emerger and is excellent in producing the natural curvature of the nymph. Use of a rabbit blend is also found in many excellent nymphal patterns such as Kauffman’s Nymphs. The blends give a more realistic coloration and the rabbit dubbing will sink easily into the water column. Andy found the the naturals had a rusty orange color that had a translucent quality. By applying the dubbing in a somewhat loose wrap, the appearance of translucency is achieved.
