I don’t tie foam flies very much anymore but when I used to, I would catch a ton of bass and bluegill on a “froggy fly” made of simple craft foam, a bit of bucktail, and some rubber legs. Recently, I taught some of the members of my fly fishing club at St. Michael High School how to tie this fly. It’s an easy fly to tie for beginners.
The materials are very simple:
Hook Gamakatsu 2/0 finesse wide gap hook 230412 or 230912 (weedless)
A small clump of bucktail
Thread (I use 210 denier for strength)
Rubber legs (use spinnerbait rubber skirts)
Craft foam (Hobby Lobby, Walmart, or Michaels
Start by putting down a thread base.
Then add small clump of bucktail and some of the rubber legs
Cut the foam in a strip about width of the hook gap and trip the tip to make a triangle to have a tie in point.
Work your thread to about an eye length behind the eye and tie down the foam.
Then fold the foam back over itself and tie in the front rubber legs.
Trim off the tail end of the foam to your liking, whip finish, and add a drop or two of some sort of head cement on the wraps and the underside to make it more durable. Then use markers to make it look like a frog.
