The Umpqua GTI Caddis, designed by the renowned fly tyer Lance Egan, is an exceptional weighted fly pattern that closely imitates a hydropsychidae larvae, commonly known as the "net builder" caddis. The GTI in the name stands for Go-To Imitation, which truly represents this fly's versatility and effectiveness as a go-to fly for anglers looking to target trout.
While this fly may not match the exact color combinations of the real insect, Lance Egan has spent a considerable amount of time tying and trying caddis larva imitations to determine what fish prefer. Through trial and error, he discovered that a contrasting shell back color works best to attract fish, despite not necessarily matching the actual colors of the caddis larvae.
With its contrasting shell back color and weighted design, the Umpqua GTI Caddis is an excellent choice for anglers targeting trout in a variety of freshwater environments. Whether you're fishing in a river, stream, or lake, this fly is sure to attract the attention of even the most discerning fish.
In summary, if you're looking for a reliable and effective caddis imitation that closely imitates the hydropsychidae larvae, the Umpqua GTI Caddis by Lance Egan is an excellent choice. With its weighted design and contrasting shell back color, this fly is designed to deliver exceptional results and attract fish in even the most challenging water conditions.
