Emerger
CDC Olive Emerger
CDC olive film-riser
Trout · GraylingFilm
CDC emerger hung in the film for olive emergences — covers the Patagonian Andesiops as well as European Baetis.
Fish this when
Fish it during an olive hatch — Baetis on European rivers or Andesiops on Patagonian water — on cool, overcast days when duns are labouring up through the film.
Why it works
The CDC fibres splay and trap tiny air bubbles the way the natural's nymphal shuck does as it's dragged through the meniscus, giving a translucent, half-drowned look a fully dressed dry can't reproduce.
