And here it comes eventually the dusk. The number of flying critters increases every minute. There is a mixed hatch:
tiny mayflies, small and large sedges share the air-space with mid-sized yellow upright mating spinners, large white Mayfly
spinners and various sorts of egg-laying caddis. It seems impossible that there is not a single fish rising now.
Our fly patches fill up but there is nothing that can bring a fish to rise. We are now trying different sizes
of emerging caddis pupa but nothing and even the wighted nymph is not working.
