    Perch Pattern

    Yellow Perch
    #1/0#2#4

    Fall is prime time for Perch patterns, as Muskellunge will actively prey on juvenile perch to gain energy for the colder months ahead.

    nymph

    Pheasant Tail Nymph

    Mayfly nymph (various)
    #14#16#18#20

    A year-round staple, the Pheasant Tail Nymph mimics various active aquatic insects and remains effective for subsurface feeding Panfish as insect activity shifts in the fall.

    Muskie Fly

    Baitfish
    #3/0#4/0#5/0

    Muskies are actively feeding in the fall to bulk up for winter, and this pattern is specifically designed to imitate their baitfish prey during this crucial period.

    streamer

    Crappie Jig Fly

    Minnow/invertebrate
    #8#10#12

    Crappie and other Panfish will be schooling around structure in the fall, making this jig pattern highly effective for targeting them during this period.

    Articulated Streamer (Drunk Sculpin)

    Sculpin

    Woolly Bugger (Olive)

    #4#6#8

    A versatile and reliable streamer, the olive Woolly Bugger effectively imitates leeches and baitfish, which are consistent food sources for both Muskellunge and Panfish as water temperatures drop in the fall.

    dry

    Blue-Winged Olive Comparadun (BWO)

    #18#20#22

    Fall BWO hatches are a key event for Panfish, and this low-profile dry fly is excellent for selective fish feeding on emerging or adult mayflies.

    dry

    Crayfish (Fly) (Olive/Rust)

    #14#16

    Crayfish are a primary food source for predatory fish like Muskellunge in rocky river environments, and this subsurface pattern is crucial for fall feeding.
