How to Tie: The Grumpy Frumpy

In this week’s “How to Tie” video feature, Cheech from Fly Fish Food ties a small stream trout killer, the Grumpy Frumpy.

Difficulty: Intermediate 

When it comes to summertime attractor dries, the Grumpy Frumpy is one that many anglers consider a favorite. Being constructed heavily with foam, this fly floats with the best of them and will certainly produce trout. On high mountain streams, whether for cutthroat trout or brook trout, this pattern is a killer. Small stream fishing with the Grumpy Frumpy will undoubtedly produce fish and will stay intact even after a long day on the water.

Many different colors can be used for this fly, but the traditional yellow and red have passed the test of time. The Grumpy Frumpy has all of the key elements that make a fly successful. Building the body with foam is a way to ensure high floatation and durability, which when paired with hackle only helps the fly ride high. Rubber legs add to the buggy nature of this attractor and allow it to take many different profiles when colors are changed.

Thinking of hot summer days and small high mountain stream fishing is a good escape from the colder months. For your next excursion, make sure the Grumpy Frumpy is on the end of your line. A 3wt setup and a hike to a river can sometimes lead you to the best memories. Escaping the crowd can be essential at high points in the year, and this fly will ensure you make the most of those days when you explore blue lines. The Grumpy Frumpy will be your best friend on the water, and might make you fall in love with small stream trout fishing.
