Flashback Foil

Reflective, realistic foil for adding shine, contrast, and trigger points to fly bodies and backs.

Add lifelike flash and contrast to your nymphs, emergers, and larvae with flashback foil. This reflective material mimics the natural shine of real insect backs and gas-filled shucks, creating flies that catch light—and fish attention.

Flashback Foil

Flashback foil is a highly effective material used to add natural shine, contrast, and visual triggers to subsurface flies. Many aquatic insects—especially nymphs, emergers, and pupae—develop reflective backs or shucks as they rise toward the surface. Flashback foil captures this lifelike effect by reflecting light just enough to stand out without overpowering the fly.

This versatile material is ideal for nymph backs, wing cases, ribbing accents, thorax plates, emergent shucks, and shellbacks. It enhances visibility, adds depth, and helps flies stand out in various light conditions, especially in fast water or during hatch transitions.

Flashback foil can be used to create:

  • Shiny wing cases on mayfly and stonefly nymphs
  • Flashy thorax plates on attractor nymphs
  • Subtle shimmer in caddis pupae
  • Realistic shellbacks on scuds and gammarus
  • Trigger points on Euro-style patterns
  • Foiled ribbing for segmented effects

Durable, easy to cut, and simple to tie in, it works beautifully with epoxy, UV resin, or varnish overlays to create ultra-realistic finishes. Whether you want subtle realism or bold attraction, flashback foil adds a proven fish-triggering element to your patterns.
