Male Tricorythodes (Tricos) Mayfly SpinnerMale Tricorythodes (Tricos) Mayfly Spinner View 3 PicturesI collected these males about 9:30 AM, air temp. about 68 degrees F. The males were flying about 3 ft above the stream flying up and down the stream rather than the typical vertical swarm you see with most mayfly males. The males are black and the females are a green color due to the eggs they are carrying. They do not live very long which is typical for small bodied mayflies. They do not fly during windy conditions. I suspect these are Tricorythodes minutus.
