Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This medium-instar nymph is about an inch long.
This is one of the earliest videos I made, and I was experimenting with a tank and background that didn't work very well.
This mayfly was collected from unknown in Wisconsin on January 12th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
