Top Secret Midge
Designed by Pat Dorsey on Colorado's South Platte River, the Top Secret Midge is a deadly midge pupa/emerger imitation. Its brown-and-white segmented body with a CDC wing gives it a realistic emerging profile that fools the most selective tailwater trout. CDC along the back keeps the fly in the subsurface without floatant, and it excels when fished deep with split shot or just below the surface film.

How to Tie the Top Secret Midge
- 1
Step 1
Place a size 20-26 curved midge hook in the vise and attach dark brown thread behind the eye.
- 2
Step 2
Wrap the thread rearward to the bend in smooth touching turns, trimming the tag end.
- 3
Step 3
Optionally tie in a short piece of amber or brown Antron/Z-Lon at the bend as a shuck, extending slightly beyond the hook bend.
- 4
Step 4
Tie in a short length of white thread or floss at the rear of the hook, just above the shuck tie-in point.
- 5
Step 5
Wrap the brown thread forward forming a slim, tapered abdomen body up to about two-thirds of the shank.
- 6
Step 6
Spiral-wrap the white thread through the body to form clear segmentation, then tie off and trim excess.
Keep the segmentation even and visible — the contrast between brown body and white rib is a key trigger.
- 7
Step 7
Tie in a small pinch of white poly yarn, CDC tuft, or Sparkle Organza at the front of the body, facing upward to mimic the emerging wing.
- 8
Step 8
Dub a tiny ball of rusty brown or gray/black dry fly dubbing behind the wing for the thorax.
- 9
Step 9
Whip finish behind the hook eye and trim the wing tuft so it extends just past the thorax.
- 10
Step 10
Apply a small drop of head cement to secure the thread wraps.
Fish this pattern just in or below the surface film as a dropper under a dry fly or small indicator. Use 5X-6X tippet.
