Just a quick knock up, no shellback used.
Tie front feelers and eyes in before you weight the hook, add lead to get shape required, cover with thread/floss. Tie mono rib and herl under hook, twist herl into a rope and pull back to eye, follow with rib, colour if needed, cover with epoxy.

epoxied
Just had a look at the pattern, he does indeed use the Pott's weave.
Quick knock up that way using ultralace instead of latex. Similar result but one takes 2 minutes to tie the other 10.
