Foam Beetle

Printable Version


The pattern is a variation of a beetle tied by Tim of Tim's Fly Shop just outside of Roaring River State Park.  Peacock herl is added to the body of the fly to provide some luster or sheen to the fly.  It is a simple beetle pattern to tie, easy to fish and is very productive.  To view a video of Tim tying a variation (no peacock herl), click on the picture of the beetle below.


Hook:Tiemco 300 Size 12
Thread:Black 8/0
Shell:Black Closed Cell Foam
Underbody:Peacock Herl
Legs:Black medium round rubber
Indicator:Yellow or orange foam

Tying Instructions

  1. Mount the hook and build a thread base on the shank.
  2. Apply glue to the thread and then tie on the strip of foam.  Leave a small knob of foam just behind the eye.
  3. Secure the foam to the bend of the hook.  Return the thread to a point just behind the eye.
  4. Tie on a clump of peacock herl along the hook shank to the bend.  Return the thread to a point one-third of the distance behind the eye.
  5. Tie on a one-half to two inch length of the black rubber leg material.  The length of rubber legs should be contain three parts and still secured together.
  6. Secure the legs with a figure-eight wrap so that they are perpendicular to the shank with the same length of rubber on each side of the shank.
  7. Wrap the peacock herl forward to the rubber legs.  Wrap the herl under the rubber legs and then in front of the legs.  The peacock herl should not cover the rubber legs, but should be tied under the shank.
  8. Pull the shellback over the shank and tie it off to the rear of the knob formed in step one.
  9. Place the indicator foam on top of the beetle and tie it off.
  10. Lift the foam shellback and form a head.  Whip finish.
  11. Trim the foam shellback and indicator foam.
  12. Cement the head.


The beetle also can be tied using brown or gray foam and can be tied in various sizes.  The indicator can be hard of various colors.  Use the color that is most visible for you.

Fishing Techniques

The pattern is best fished when terrestrials are on the water - July, August and September.  Cast the fly to sighted fish or to a likely lie.  Plopping the beetle on the water seems to attract fish for some distances.  Strikes can be vicious.
