The Stimulator fly is a popular and effective dry fly used by fly anglers for trout. The fly imitates adult stoneflies, caddisflies in smaller sizes and larger terrestrial insects.

In The Professionals’ Favorite Flies (1993) Lefty Kreh praises the Humpy as:

The Humpy is one of the best flies ever invented for turbulent water where many dry flies are quickly drowned. It is not a specific imitation of an insect, but rather is a suggestive pattern that looks buggy, floats like a cork and has fooled thousands of trout. It is a fly that every serious western trout fisherman carries (and many eastern anglers are finding just as effective). I would never go trout fishing anywhere—Chile, Argentina, New Zealand, Europe—with a few Humpys in my box.

— Lefty Kreh

Origin

The Humpy style originated with an early 19th century fly called the Tom Thumb which was being tied in both the Eastern U.S. and Canada as well as England as late as the 1940s. The Tom Thumb was a dry fly with two opposing clumps of deer hair over a colored thread body.

The Tom Thumb style was adapted in the late 1940s by California angler Jack Horner into a pattern he called the Horner Deer Hair fly, the first version of what is called the Humpy today. When the pattern was introduced to fly shop owners in Montana in the 1950s, the pattern became known as the Goofus Bug. Wyoming anglers started calling it the Humpy and the name stuck.

Imitates

The Humpy is an attractor style dry fly that imitates no particular prey for trout. Its buggy appearance can resemble adult mayflies, caddisflies, stoneflies or terrestrial insects like grasshoppers.
