How to Rig It

Drop 18–24" below a small indicator or as a trailer behind a heavier nymph.

How to Present It

Dead-drift through deep slow seams and tailouts. The slower the better in winter.

Why It Works

Midges hatch 365 days a year and are the #1 winter food source for trout. The slim profile and tiny tungsten bead get it down fast in cold, slow water where trout are stacked up.

History

Tied by Ted Welling on the San Juan River in the 1990s, the Zebra Midge spread quickly because it's almost impossible to tie wrong: thread, wire, bead. Three materials, infinite trout.

Pro Tip

Carry red, black, and olive in #18-22. If they refuse one color for 20 minutes, swap — color preference shifts daily on tailwaters.

Frequently Asked Questions

What size Zebra Midge should I use?+

Start with #20 in black with a silver bead. Drop to #22 in clear winter tailwaters; bump to #18 when flows are stained.

Is the Zebra Midge a nymph or emerger?+

It is a midge pupa imitation fished as a nymph, deep and slow on the bottom.

What tippet for a Zebra Midge?+

6X fluorocarbon. Fluoro sinks the fly faster and is nearly invisible to picky tailwater trout.
