Wyoming's Gray Drakes and Brown Stoneflies

July 7, 2005 By: Marshall Cutchin

Northern Wyoming doesn’t share most of the big-bug hatches that lure anglers to the Yellowstone and other Montana rivers this time of year, and that’s just fine with folks who enjoy the relative solitude of the Big Horn Mountains. “When we arrived at the stream there was a lot of cotton wafting in the air from nearby cottonwood trees. I remarked to Alex and John about the high amount of cotton in the air. They pointed out that the “cotton” was managing to go against the breeze. I had misdiagnosed a mega hatch of brown stoneflies.” Bob Krumm in the Billings Gazette.
