Fleye Foils

Published Oct 8th 2012

These new fish foils from Bob Popovics are really great for making baitfish imitations.



Bob Popovics has been breaking new ground in saltwater fly-tying for decades introducing new patterns, new tying methods and not least new materials - or at least new use of known materials.
His book Pop Fleyes features a number of these patterns and techniques, but recently Bob introduced yet another material: Fleye Foils.

The Fleye Foils are small fish shaped foil profiles, which come in three shapes and many sizes.
The color and structure is the same for all foils. Very shiny and reflecting light in a multitude of colors. The foils have printed eyes and gills on them and in some cases mouths, meaning that the finished fly will become a pretty good imitation - at least where the foil is visible.
The foils come in sheets with a number of adhesive fish heads/bodies, ready to peel off and glue to your fly. After having attached the two foils to the side of your materials you take a few wraps over the tip of the foil, finish the thread and then cover the foil and materials with epoxy, light curing resin or another clear substance.
The result can be a very convincing baitfish imitation.

Many shapes and sizes
The foils come in three shapes and each shape comes in several sizes covering hook sizes from very large (size 4/0) down to fairly small (size 6), which covers a large span of baitfish sizes.
The shapes vary a bit, and are called Bay Anchovy, Silverside and Sand Eel. These differ in shape, predominantly in width (height) the Bay Anchovy being the tallest and roundest and the Sand Eel being the slimmest.
None of them are really fish shaped, but will make up the front part of the of the body and the head of the fish that your fly will imitate. You can make lots of variations to your flies by varying colors of the other materials used, using colored resin or resin with flakes or even using a marker to color the foil itself before covering it with epoxy or LCR.
In general the Surf Candy style of flies will be perfect as a base for the foils, in other words: slender and sparsely dressed flies.

Tying with the foils
When you tie with the foils they are usually the second last step, the last step being epoxy or some other resin.
In other words: you tie your fly, stick the foils on the outside of the materials and coat the foils and the materials with a layer of translucent material that holds everything together and creates a shape.
The foils are sticky on the backside, which aides the process and also have a small tip that you tie in under the final wraps of tying thread. This both secures the foil and curves the it a bit.
Once it's stuck on the fly and the thread has been cut, you apply the coating in one or several rounds to create a body shape and secure the materials.

The price is US$ 6.99 or Euros 5.60 for a pack with 24 foils of the same size, yielding 12 flies, so these are not the cheapest materials, but on the other hand they do give you a shortcut to some very nice baitfish imitations.
The foils are widely available in the US. In Europe they are distributed by The Fly People in Germany.
You can also find Fleye Foils on Facebook.
According to the distributor Bob Popovics has some new additional stuff in the pipeline. There will be more shapes and additional materials to make the Fleye Foils even more useful.

My first pattern
I have often tied flies to imitate sand eels, which are very common here and a top food item for the sea run trout that I fish for. Using Fleye Foils it's easy to get an imitation that looks pretty much like the real thing and certainly behaves very fishy in the water. I have tied it small. These fish often appear in large schools of individuals just and inch or two long, but can grow to 10 inches or more.
I have used very shiny and translucent Polar bear hair for the belly, but I realize that this isn't a common material. Use white bucktail or a synthetic in stead. Keep the fly very sparse and cover just the front part with resin.

TypeCold saltwater fly
Martin Joergensen
Year of origin

HookScierra stinger hook size 12 (corresponds to ordinary hook size 6-8)
Thread6/0 chartreuse
BellyPolar bear (use white bucktail as a substitute)
WingOlive bucktail and a couple of straws of smooth pearl flash
ToppingTwo peacock herl
SidesBay Anchovy Fleye Foils size small
CoatingBug-bond Light Curing Resin

Tying instructions
  1. Start the thread close to the hook eye leaving a little space
  2. Tie in a small bunch of Polar bear (or white bucktail) about 4 times the length of the hook under the shank
  3. Tie in a small bunch of olive bucktail slightly longer on top of the shank
  4. Top with a couple of peacock herl
  5. Attach Fleye Foils to the side of the fly, making sure the small protrusion on the foil flushes with the bare shank right behind the hook eye
  6. Catch these protrusions with the thread
  7. Cover and build a small head
  8. Whip finish and cut thread
  9. Pull back materials tightly and cover fly front and foils with a UV resin such as Bug-Bond
  10. Distribute the resin to form a slender body
  11. Harden with UV light

Even though we're a popular site and I'm almost sure that Popovics has been looking in at some point, I'd be very (positively) surprised if he answered your question here.

But maybe I can help you. If you want to catch trout with a Fleye Foil fly you can use any of the foils. I honestly think the trout cares very little about the shape of the foil. If you want to imitate a trout the Anchovy or the Silverside will probably do the best job.

I am tying fly for my own use and since Bob Popovics has ben tying this type of fly I should like to ask him which of the
" Silverside, Sand Eel or Bay Anchovy " can be used for trout fly.
I loock forward to this answerd, Thank's.

Best Regards Odd - Julian Martinsen ( NORWAY )
