Caddis Pupa The Caddis Pupa represents one of the most important stages in the caddisfly life cycle and is a pattern every trout angler should carry. Unlike mayflies and stoneflies, caddisflies undergo complete metamorphosis, progressing through four distinct stages: egg, larva, pupa, and adult. As caddisflies transition from larva to adult, the pupa stage becomes highly vulnerable as the insects rise through the water column toward the surface. Trout often key heavily on these emerging pupae, feeding aggressively during caddis hatches and intercepting them before they reach adulthood. This pattern effectively imitates that critical emergence stage, offering a realistic profile and movement that trout recognize as an easy meal. Fish it under an indicator, dead drift through likely holding water, or allow it to swing at the end of a drift to imitate a naturally ascending pupa. Key Features• Realistic caddis pupa profile• Represents a key stage in the caddis life cycle• Effective during caddis hatches• Excellent for rivers, streams, and tailwaters• Productive under indicators or swung in current• Proven trout-catching pattern throughout the season ImitatesEmerging caddisfly pupae. Available Sizes#10, #12, #16, #18, #20 When trout are feeding below the surface during a caddis hatch, the Caddis Pupa is often one of the most productive flies you can fish.
