The early season caddis hatch is one of the finest hatch cycles and a perfect season kick-off. Even if they are moderate in size, the first real hatch of the season might lure a nice trout or grayling trouts to the surface. In Trysil (Norway) there is an exceptional early caddis hatch. Just a few weeks after the ice melts, just when the stoneflies are peaking, the early season caddis hatch starts. It usually start in mid-May, and continues for about three weeks.
