Fly of the Month: The Yuk Bug

The Yuk Bug fly pattern can be used year-round to fish for everything from trout to smallmouth bass and steelhead. This big buggy-looking nymph has rubber legs that create a lot of action and imitates a lot of different fish foods including stonefly nymphs. They can be very productive patterns when hatches of big stoneflies are happening.

Try dead-drifting it under an indicator, with a beadhead dropper behind it, or fish it by itself and try twitching it off the stream bank. Stoneflies swim toward the banks after they’re released from their hold, and twitching the line creates a tremendously lifelike action on the legs of the fly. If you need to get deeper use the conehead version which will ensure that the fly sinks to the bottom. Fish on!
