If I had to fish with a single dry fly pattern, I’d definitely choose the Parachute Adams. It’s worked well for me on rivers ranging from Oregon to Michigan. Last weekend, I did well with it on the Little Jordan, a small creek in southeastern Minnesota.
I suspect I’ve caught more trout on the Parachute Adams than on any other dry fly pattern, though the Elk Hair Caddis is a close second. Here is a profile of this remarkably effective pattern:
1. How it originated
The Parachute Adams is a modification of the Adams.
According to Paul Schullery, the Adams originated in 1922 in Michigan. Leonard Halladay developed it as a general mayfly imitation, and his friend, Charles Adams, used it successfully on the Boardman River near Traverse City, Michigan. As a result, Halladay decided to name it after his friend.
The Adams is a relatively simply pattern to tie. It consists of dark gray dubbing for the body, brown and grizzly hackle, grizzly hackle tips for the wings, and a mixture of brown and grizzly hackle fibers for the tail.
Bud Lilly observed that the Adams grew lighter when it went east. But when it went west, fly tiers used extra hackle—presumably to keep it floating longer in the swift currents of western rivers.
2. How it has been modified
The Parachute Adams uses the same hackle, dubbing, and tail as the Adams.
However, the modification comes in the hackle (front) section of the fly. An Adams pattern wraps the hackle around the hook vertically—up and down. However, the Parachute Adams contains a vertical post of white calf hair at the front or head of the fly. Then, hackle gets wrapped horizontally around the base of the post. Tiers refer to this as “parachute style”—hence the name Parachute Adams.
There is no wing added as in the traditional Adams pattern.
The Catch and the Hatch has produced a helpful instructional video for tying this pattern. Even if you are not a fly tier, it’s worth watching so you can see what makes this fly work.
One of the more recent modifications to the Parachute Adams is the Purple Haze. This is the exact same pattern with a purple body instead of a dark gray one. It gives trout a bit different look, and I’ve had success with it.
However, I keep reverting back to the time-tested Parachute Adams — especially on rivers where the Purple Haze has become a craze so that trout are seeing nothing but purple.
3. Why it works
Like the standard Adams pattern, the Parachute Adams works well because it is a general mayfly imitation. It is versatile enough to serve as an attractor pattern when nothing specific is happening on the surface. Yet I have done quite well with it during specific hatches like Blue-Winged Olive (BWO) hatch. Some fly fishers even swear by it as an option for the Caddis hatch.
Perhaps it works well, too, because it is a low-riding fly. This gives trout a good look at it as it remains suspended in the surface film where mayflies typically emerge.
One of the most important factors in its success is its visibility to fly fishers. I can see its white post, or parachute, even in low light.
4. When to use it
You can use the Parachute Adams, well, whenever you want to catch trout on a dry fly. I’ve caught trout on it in every season of the year—even in the winter when a size #18 or #20 can imitate a midge cluster.
Unless I suspect that trout are keying in on Pale Morning Duns (PMDs) or on Caddis flies, I’ll tie on a Parachute Adams when I see rising trout. Typically, I like a size #18 or even a size #20 when a hatch is on.
I’ll tie it on, too, when no hatch is happening and I’m trying to coax a trout to the surface. In these cases, I typically use a bit larger size—either a size #14 or #16.
The Parachute Adams is a terrific choice for your number one go-to fly. Don’t leave home without it.
