This is a flexible pattern that’s intended for Steelhead but it works for all of our lake run fish. Intruder style flies are designed to create a large profile with minimum materials. The takes on this style of fly can be electrifying and it swims like a champ. They don’t look like food but their spider like profile and movement create a territorial type of strike. I can’t wait to start experimenting with spinning ostrich herl and lady amherst in a dubbing loop for this style of fly. Also, if you spin some deer hair before palmering marabou or spinning composite hackle it makes a great back stop to help the longer materials create a larger profile and keep them from collapsing.
