The ‘black spinner’ mayfly was out and about by mid-October.
The tough thing for these fellows is consistency of weather in spring. Warm afternoons and light winds and the love life.
A cold shower or two and the hatch stops or they get blown off the surface too quickly for the fish.
However, it always delights the dry fly enthusiast to see them out in numbers as Andrew discovered with this delightful wild brown picked up on the mayfly emerger.
