Why are Attractor Fly Patterns Effective?

I’ve been sitting at my fly tying vise this week working on flies for our upcoming trip to Patagonia. All the flies are Fat Alberts in a couple of sizes and colors. My mind wanders a lot when tying and I started to think why are attractor fly patterns effective?

I featured this fly last year as a Throw Back Thursday Fly. I found it was initially used to imitate Cantaria beetle in Chile. But why would it be effective in a lot of other waters?

Sure, I can understand how a large black fly might trick a trout into thinking it was eating a beetle, but why eat a brown/tan version? I know what you are thinking…grasshopper, right?

Here is a link to my RiverKeeper Flies YouTube channel where I demonstrate tying the fly.

Or if you like to be entertained, here is a video of me “speed tying”. I have a 30 minute limit on my camera when creating videos and decided to see how many I could tie. It’s just over 5 minutes long.

When I think about attractor fly patterns, the one that comes to mind is a Parachute Adams. I don’t use it much, but I know other fly fishers do with great success.

How about a Purple Haze?

Or this Royal Wulff?

Or a Chubby Chernobyl in purple?

Why are they successful? I’m not sure.

When matching the hatch, I generally use the theory of size, profile, and color as the basic characteristics to consider when selecting flies. I believe the order is important.

I don’t have a lot of answers, only questions.

Back to the vise so random thoughts can bounce around in my head! I have a few more size 8 Fat Alberts to tie in black.

Enjoy…go fish!
