Intruder style flies are designed to provoke aggressive strikes from steelhead.
As the name suggests, the idea is to "intrude" on the steelhead's territory and trigger the "fight" response of fight or flight.
Meahan's Intruder is approachable pattern for all fly tyers. So many Intruder fly patterns call for some exotic material, but with everyday materials Meahan's Intruder is a good fly for beginning steelhead tyers, but also a quick, good-looking fly for veterans as well.
