Sulphur Dun’s begin hatching in the mid to late afternoon. The Sulphur Dun floats on the surface a while before they are able to fly away, so they are especially vulnerable to trout at this stage. Males and females differ in body color somewhat, with males displaying a yellowish-tan body and females a more golden color as they are full of ripening eggs. So pay attention to what Sulphur’s are emerging and changing up your pattern body color as well. Sulphur’s can last quite a while on-stream and begin in the middle of the afternoon. One of Michigan’s best hatches, and fish of all sizes really start to look up for this aquatic insect.
