The HMB....The High Mountain Bug.
this fly is very easy to tie and very effective in little mountain streams...browns ,bows and specially brookies love it.You can use black, dark grey or grizzly hackles to tie it on a 16 or 14 hook.As for the "signal" wing fluo orange or green parapost is OK.
1 fix three peacock herls.
2make the body and fix the parapost fibers.
3cut the fibers and fix your hackle.
4turn the hackle,finish your fly....that's all folks
PS...I put a drop of superglue ....on the head.
