Simple, buoyant and deadly effective. Willow Grubs are a favourite among trouts' various food sources, so when the hatch is on, the fish are too!
Willow grubs are tiny maggot-like larvae of the sawfly family of insects that drop from their leafy cocoons and into the water. At the height of this activity, trout have eyes for little else. This humble foam dressing is a dead ringer for the unfortunate naturals. When trout are seen gentle dimpling, or lined up behind overhanging willow branches then reach for this little number. A sighter wing/post obviously helps you locate the whereabouts of your artificial to address unwanted drag and of course determine when a trout takes your fly.
