A tiny, deadly midge pupa/emerger with a built-in trigger. The Glass Beadhead Mercury Red uses a clear “mercury” bead that mimics an emerging gas bubble and a slim red body for contrast—perfect for cold, clear conditions and picky trout.
-
When it excels: Late fall through spring on tailwaters and spring creeks; overcast days; soft seams, slow runs, and pool tails
-
Why it works: Glass bead reads like a natural air bubble during emergence; red abdomen adds a hot-spot cue while the slender segmentation keeps the profile realistic
-
Pack size: 3 flies
-
Targets: Trout (rainbow, brown, brook)
-
Ready to fish: Sparse, durable tie with consistent proportions for subtle, drag-free drifts
How to fish it
Dead-drift under an indicator with light tippet or tightline/Euro with steady contact; adjust depth until you tick occasionally. During active midge hatches, run it 12–24" below a small dry (griffith’s/CDC midge) or suspend it mid-column; finish each drift with a gentle lift to suggest the ascent.
Care
Rinse after use and air-dry before boxing to prevent hook corrosion.
Satisfaction
30-day returns/exchanges.
