This classic design will bring fish to the surface during the Spruce Moth hatch. The Antron tail provides a sparkle that’s unavailable with other material;s, and it looks alive to the fish. This is also a fairly easy fly to sink, if you don’t use floatant, so when the fish are reluctant to come to the surface, tihs fly will go to them.

Spruce Almighty

The CDC body and wing bring a realism to this fly. The Elk Body wing helps keep it afloat, but it’s a low floater, and sometimes that’s exactly what the trout want. Make sure to use the proper floatant- Dry Magic or Loon Lochsa- on the CDC, or the feathers will mat down and the fly won’t be effective.
