A triumph of alliteration. Original had a dubbed egg sac, but I like foam so much better.

hook - Dai Riki 280 #10
thread - UTC 140 hopper yellow
egg sac - 2mm foam black
feelers/antennae - rubber small black
overbody - 2mm foam brown
abdomen/thorax/head - Fly Rite quill gordon
ribbing - tying thread
wing - elk hair
legs - butt ends of elk

Part 1

poke a hole in foam (1/2 gap width), slide on hook

start thread, wrap back to bend; fold foam over, top and bottom, tie down and trim

add feelers on either side of egg sac

taper foam strip (not quite gap width) and tie in; Super Glue and tie down
