Deer hair or Antron (overwing/wing pads) Dark brown mink guard hair (few fibers)
Dubbing (thorax/collar) Brown dubbing (small pinch)
How to tie it
Seat the black bead at the eye and lay a thread base to the bend.
Tie in bright green Ultra Wire and wrap it forward in touching turns to the 70% mark for a segmented abdomen; tie off and helicopter to break.
Tie a sparse veil of amber/green Antron over and under the abdomen, left loose so it traps air like the natural's gas sheath; trim it to about the hook point.
Tie a few fibers of dark brown deer hair or Antron over the top, back to the rear of the body, to suggest the dark wing pads.
Dub a short brown thorax behind the bead and sweep the fibers back.
