Another sulphur for comment 1 Reply »
And this one, also from the midwest, is more green than the sulphurs I recall seeing this season. My limited experience in PA streams suggests that many, if not most, of the sulphurs here are best imitated by pale yellow, bright yellow, or orange bodies. Gene, and others, am I far off?
