How to tie it
Form a slim extended body of blue foam or blue thread/floss over-wrapped with clear mono for segmentation, projecting well past the bend to mimic the long damsel abdomen.
Tie the extended body onto the shank and add prominent melted-mono eyes behind the hook eye.
Tie in a sparse wing of clear/white synthetic fibers, splayed low over the back.
Wind a grizzly or blue-dun hackle for legs and flotation, two or three turns.
