Flashback Hare's Ear Nymph
An excellent general searching nymph, mimicking various aquatic insects active subsurface and appealing to opportunistic trout feeding below the surface.
October Caddis
This large caddis species represents a significant fall meal for trout, actively hatching in the autumn months on freestone rivers.

Buy at AmazonBlue-Winged Olive Comparadun
A quintessential fall dry fly, perfect for matching the intermittent BWO hatches that often occur on overcast days and in the warmer parts of the afternoon.
Blood Dot Egg
With fall being a spawning season for some fish, egg patterns are highly effective for opportunistic trout that will feed on loose eggs in the drift.
Buy at AmazonZebra Midge
Midges are a primary and consistent food source in rivers year-round, and a black Zebra Midge fished under an indicator or as a dropper is a reliable choice for picky trout.
Buy at AmazonHellgrammite Fly
Hellgrammites are a consistent, high-calorie food source for Smallmouth Bass in rocky rivers, making this a reliable subsurface pattern to fish near structure.
Woolly Bugger (Olive)
This versatile streamer effectively imitates leeches and baitfish, both crucial food sources for predatory Rainbow Trout and Smallmouth Bass as they become more aggressive in cooler fall waters.
Schroeder’s Parachute Hopper
While late in the season, terrestrials can still be effective on warmer fall days, acting as a large attractor for opportunistic trout along grassy banks.
