Our most celebrated of upwinged species the Mayfly has been hatching for a few weeks now. Obviously, in the South things kick off a week or two sooner than they do further North. The Eden is currently experiencing a surge in Mayfly activity and thankfully our local trout population relish such a mouthful. Only the other day I watched a steady trickle of Mayfly drift down a pool on Eden's middle reaches. Ashamedly caught out for once, with my mayfly box lying in the car, a size 10 tan Klinkhamer came to my rescue. Nine trout couldn't resit a carefully presented fly the best of them going a respectable 1lb 12oz.
