Female Baetid spinners were abundant subsurface looking for substrates to lay their eggs, and they found my waders. I'll update the ID for this picture after identifying the
associated male spinner. I caught several fish on a small brown soft-hackle fished as a crude imitation of these spinners before the fish all started taking
Tricorythodes spinners instead.

Male Baetis tricaudatus (Blue-Winged Olive) Mayfly Spinner
View 12 PicturesSome notes from identifying this specimen under the microscope:
1. The hind wing has three longitudinal veins (Longitudinal vein: Longitudinal veins are the major long veins running length-wise through an insect's wing, connecting the base to the outer margin, or the major branches from those veins.), but the third is faint, short (about half the length of the wing), and close to the wing margin.
2. Then antenna is brown fading into white at the tip, and the base is ringed with white.
3. The joints of the tarsal segments on the middle and hind leg have fine black markings.
It was also collected in association with a female spinner. Quick Reply
