We've managed to bookend our weekly trips to Boston with some outstanding evening fishing the last two weeks. Our fishing has been late afternoon into dusk and with anywhere from 5-10 bugs on the water; 90% of the fishing has been with dries!
We have seen large sulphurs, small sulphurs, light cahills, gray foxes, blue-winged olives (several species), isonychias (slate drakes), yellow drakes, paraleps, dark blue sedges, cinnamon caddis, and black midges. The mayflies have been both duns and spinners depending on the evening.
The trick has been to figure what the trout are feeding on at any given moment, and being observant enough to notice when they switch from one bug to another. Some nights they have stayed on one insect, and others they have stitched from one to another to another. Of course, if that isn't enough, one fish may be feeding on the emerging cinnamon caddis, while another is feeding on sulphurs! Most evenings we have had to use 6X tippet to get the drift we need and catch fish.
It's been loads of fun and challenging.
Sharpen those hooks as you fish, and you'll definitely hook and land more trouts!
