History & Lore

'GTi' stands for Go-To Imitation — a bit cheesy, but earned. The GTi Caddis is more imitative than most of Lance Egan's patterns; it represents the Hydropsychidae 'net-builder' caddis found in rivers across the country. The curious detail is the shellback: it deliberately contrasts the underbody rather than matching the natural insect. Lance has tried every realistic color variation, and the contrasting-back versions consistently out-fish them. Why? He doesn't know. But the fish agree.
