Built to Move Like a Real Egg
Standard egg patterns are tight little balls of yarn. They look like eggs sitting still, but eggs in current don’t sit still.
The Nuke Egg uses a loose, translucent outer veil over a denser color core. Once it’s wet, that outer veil flows back and softens, giving the fly a milky, drifting look closer to a natural egg moving through the water instead of a hard ball of color.
UV Core for Low Light
Steelhead and salmon are often most active early in the morning, on overcast days, or in deeper, darker runs. The core of this fly is UV reactive, which adds visibility in exactly those conditions, on top of the fluorescent orange or pink already doing the work in clear daylight.
Soft Texture, Better Hookups
This fly feels soft and a little squishy, closer to real roe than a hard yarn egg. A softer texture gives a fish more reason to hold onto the fly for a moment longer than it would a stiff one, which is usually what you need to get a clean hookset.
Picking a Size
Use the #10 (6mm core) for high, stained water or more aggressive steelhead. Use the #14 (4mm core) for low, clear water or spookier resident trout.
How to Fish It
Dead drift it near the bottom under an indicator, the same way you’d fish a weighted nymph. Most eggs do their work in the last few inches above the riverbed, so keep it close to bottom rather than letting it ride high in the drift.
For a two-fly rig, fish this as your point fly and trail a smaller nymph like a size #16 Tungsten Jig Nymph or a Zebra Midge 12 to 18 inches behind it on 3X or 4X Fluorocarbon Tippet. The egg gets noticed first, and the smaller fly often gets the eat.
Common Questions
What sizes should I use? The #10 (6mm core) for high, stained water or aggressive steelhead. The #14 (4mm core) for low, clear water or more cautious resident trout.
Is this fly just for steelhead and salmon? No. It’s common for both, but it also works for rainbow trout, brown trout, and can draw carp during the spawn.
Can I add scent to this fly? Check your local regulations first. Many fly-fishing-only and catch-and-release waters specifically prohibit scent added to flies, regardless of whether it’s applied at the vise or on the water. We don’t recommend it.
What season works best? Spring runs (roughly February through May) and fall runs (roughly September through November), matching steelhead and salmon spawning windows in most regions.

I’ll be honest — I wasn’t sure about this one when I first saw it. Egg flies always seemed too simple to me. Then I fished it below a spawning area during fall and it was the most productive fly in my box for three straight days. The soft milking veil is the key — it gives the egg that translucent, slightly fuzzy look that real eggs have when they’re fresh. Fish don’t just inspect it, they crush it.
