Perdigon Flies Quick Picks
Best All-Around Perdigon: Lite Brite Perdigon Fly - A slim, fast-sinking profile that gets to the bottom of deep runs and holding water in a hurry. It's not tied to imitate one specific bug, which makes it a reliable attractor when you're not sure what trout are feeding on.
Best for Heavy, Fast Water: Spanish Perdigon Fly - Born out of European competition fly fishing, this pattern is built to punch through fast current and reach fish holding deep. Reach for it when standard nymphs are getting swept past the strike zone before they sink.
Best for Extra Flash: Lite Brite Perdigon UV Fly - The UV-reactive body adds a flash trout can key on in low light, off-color water, or deep, shaded runs where a duller pattern is harder to spot.
Best for Matching a Sulphur Hatch: Sulphur Perdigon Fly Pattern Video Material Kit - Everything you need to tie a Perdigon sized and colored for sulphur mayfly nymphs, useful for tailwaters and freestones where that hatch is a season-long staple.
Best for Tying Your Own: Perdigon Fly Tying Video Material Kit - A complete kit for building your own Perdigons in the size and color that matches what's working, at a fraction of the cost of buying flies one at a time.
How to Choose Perdigon Flies
Sink Rate
Tungsten bead, slim profile: The defining feature of a Perdigon - a slick, resin-coated body with almost no drag lets the fly knife through current and reach depth faster than a standard dubbed nymph.
Larger or denser beads: Choose a heavier bead size when fishing faster or deeper water where you need to get down within the first few feet of the drift.
Color
Natural olive, brown, or tan: A safe, general mayfly-nymph imitation for pressured or clear water where fish are looking closely.
UV or flashy finishes: Worth trying in stained water, low light, or when fish are actively feeding and a little extra attraction helps the fly get noticed first.
Size
Sizes 14-18: Covers most general mayfly nymph imitation and is a strong starting point for searching water.
Sizes 18-22: Sizes down to match smaller naturals like sulphurs or picky fish keying in on a specific hatch.
On-the-Water Tips
Use it as your anchor fly: The fast sink rate makes a Perdigon a natural choice for the point position in a Euro nymphing rig, getting the whole leader down quickly.
Keep contact through the drift: Because Perdigons sink so fast, staying tight to the fly with a Euro nymphing leader or tight-line technique will get you far more hooksets than a slack indicator drift.
Fish it in tandem: Pair a Perdigon as the point fly with a lighter, more natural nymph as a dropper to cover both fast-sinking and subtler presentations in the same drift.
Match hatch timing with color: Swap to a hatch-specific color, like a sulphur or PMD tone, during the weeks that mayfly is actually emerging on your water.

Perdigon Flies FAQs
Q: What makes a Perdigon different from a regular nymph?
A: Perdigons are tied with a slim, resin- or UV-coated body instead of dubbing, which sheds water resistance and lets them sink much faster. They're built for speed and depth rather than exact imitation of a single insect.
Q: What size Perdigon should I use for Euro nymphing?
A: Sizes 14-18 cover most general nymphing situations, while 18-22 works better on smaller naturals like sulphurs or midges. Start larger as a searching pattern and size down if fish follow without eating.
Q: Do Perdigons work as an indicator fly, or just for Euro nymphing?
A: Both. Their fast sink rate shines in tight-line rigs, but they also work as a heavy point fly under a strike indicator.
