As I continue to pore through Gary LaFontaine’s masterwork Caddisflies, I’m reminded of the sheer volume of universal concepts that apply to fly fishing. So, even though he’s talking about fishing for trout that are feeding on caddisflies, LaFontaine could easily be talking about stripers feeding on sand eels or grass shrimp. A true maverick, he isn’t afraid to think or act differently, to challenge conventional wisdom, or conduct experiments to prove his theories. (Listen to the science. You’ve heard that one before) The more you fish for trout and stripers, the more you begin to see patterns and similarities between the species and how you should be fishing for them. Here are three themes in Caddisflies from which I think striper anglers and fly tyers who want to dramatically elevate their game could benefit.
Realism is the least important factor in fly design. I don’t have the actual stat, but I’m comfortable in saying that nine out of ten striper baitfish patterns feature glued on, ultra-realistic eyes. (Other than on these pages, when was the last time you saw a squid fly without big googly eyes?) If realism, from eyes to full-bodied profile to opacity to exact coloring, etc., is so important, how come my baitfish flies (and yours, and everyone else’s) continue to catch stripers long after they’ve literally been ripped to shreds? It’s a rhetorical question, but I’ll answer anyway. It’s because the bass are keying on certain bait or environmental characteristics that serve as bite triggers, and those triggers are still present in the remnants of the fly. LaFontaine knew that making a favorable impression on the fish — by showing them at least one primary feature or action that identified the fly as something that looked like what they were eating — was far more important than rendering a carbon copy.

Energy efficiency is the reason for selective feeding. Fish, especially bigger ones, are essentially lazy. So when they’re glommed onto grass shrimp in a feeding lane, you can engage in the futile activity of ripping and stripping a big fly past them, or deliver what they’re eating to their waiting mouths. This is why there is no one-size-fits-all “go-to” striper fly — and why learning presentation with a floating line is so important. Match the hatch, learn its nuances, make it easy for the stripers to feed, and you’ll catch more bass.
Fish are not intelligent. There is no such thing as an educated striped bass. Fish cannot reason. They are programmed for survival, and these primal forces have nothing to do with fly fishing or why you can’t fool that lunker. The fish is simply doing what’s it’s doing, and it’s up to you to crack the code.
