In the Catskills, you'll usually see your first Sulphers (there are many) in June.........and then they will continue, (different ones), all the way thru Aug. varying in size (#16 to #10), and color.....some more yellow, some more orange. i've had some spectacular eve. Sulpher hatches....."spinner falls".....both on the Willowemoc, the Neversink, and the Beaverkill.
