Mouse Fly Pattern (TMC 8089 + Weedguard)
Big trout don’t sip. They hunt.
Our Mouse Fly Pattern is a topwater predator magnet built for explosive eats and heart-stopping takes. It’s spun with deer hair for a buoyant, natural profile that pushes water, throws a clean wake, and stays floating even after getting mauled.
Tied on the legendary TMC 8089, this fly has the huge gap and strength needed for big fish and hard takes — from river browns to toothy pike. A built-in weedguard helps keep it fishing clean around banks, grass, wood, and structure where the biggest predators live.
Whether you’re skating it at night, twitching it under cutbanks, or waking it across glassy water, this fly delivers consistent action and performance in tough conditions.

FAQ
What makes the Mouse Fly Pattern effective for big fish?
The TMC 8089 base with a large gap and strength allows it to withstand hard takes. The deer hair provides buoyancy and a natural profile that mimics prey, attracting aggressive fish.
Does the weedguard affect the fly’s action?
The weedguard improves performance in vegetated areas by preventing the fly from snagging on grass or weeds, allowing consistent movement and presentation.
Can this fly be used in still water or only in moving water?
It performs well in both still and moving water, especially when used for topwater action like skating or twitching under cutbanks.
Stewart James –
This mouse fly delivered big strikes on a cold morning. The deer hair stayed floating even after being taken, and the weedguard kept it from snagging on reeds. Great for river browns and pike.
Anne Walsh –
Fished it at dusk on a glassy lake and got a solid take from a large trout. The wake it creates is natural and the fly stays up well. Highly recommended for topwater hunting.
Joseph Dyer –
Solid performance in grassy areas. The weedguard helps a lot when fishing near banks. A bit heavy for light fishing, but perfect for targeting big predators.
James Ince –
Used it in a fast-moving stream and got multiple takes. The TMC 8089 base holds up well under pressure. The deer hair gives it a lifelike profile that fish respond to.
