I love egg patterns. Its fun after a season of tying dark, or dull earth-toned flies to reach for yarn that looks more like cotton candy than tying material. In an effort to find some slightly less intense colors of egg yarn a few weeks ago, I came accross a material called "McFlyfoam." I asked the fly shop employee (who I knew was a guide) how well the stuff works for eggs. "Amazing" was his response. He demonstrated one for me…..AMAZING was right! This stuff creates great-looking eggs, at lightning speed. Its available in all the right colors, and really should be a part of your material wish list if you plan on tying eggs any time soon. It was his suggestion to create the "eye" or "blood spot" using a permanent marker~in the interest of keeping it fast. I don’t have any permanent markers that color/size, so I create it the old-fashioned way. Since some tiers omit them anyway, i’m sure both methods are fine.

Tying The Easy Egg Fly Pattern

Hook:Caddis/scud type size#12 (or to suit)
Thread:8/0 (fire orange here)
Material:McFlyfoam
Eye/blood spot:egg yarn

Tie on a thread base at the center of the hook shank. Open the pack of McFlyfoam and unfolf the material so that all the strands are going in one direction. Pull off a clump about 1/2" in diameter, slightly larger than the diameter of egg yarn. Cut two pcs. about 1-1/2" long. (this length can be reduced as you become familiar with the material) Tie it, centered onto the thread base on the top of the hook shank.

Roll that bunch around to the back, tie the second bunch opposite the first. (top view)

Make several "figure-8" wraps of thread to secure it.

Cut a length of egg yarn, about 2" long. Pull a fine strand of egg yarn half the diameter of the finished dot you want. Loop it around the tying thread, and tie in at the center of your foam wraps. Stroke all the fibers back, tie your finishing knot. (I use 3 half-hitches)

Stroke all the material up, being sure that you’re stretching the McFlyfoam. As long as the egg yarn fibers are under some tension, and the McFlyfoam is under as much as you can manage, the result will be nice and round.

Cut as shown. The closer to the hook shank you cut, the smaller the egg will be. Very small, or very large eggs will require that you adjust the amount of foam you use. Pinch and roll around the hook slightly if the egg does not cover the shank all the way. Trim the egg yarn slightly if it ends up longer than the foam fibers.

Egg-sucking leech-McFlyfoam style!

To use this material in an egg-sucking leech, create your wooly bugger leaving 3/16"-1/4" behind the eye. Change to a lighter thread, and create the egg in the same manner. Any foam color or combination can be employed on this pattern. Good luck, go get ‘em!
