Female Tricorythodes (Tricos) Mayfly Spinner Pictures

 I photographed this Trico alive, although it didn't have much time left. These things die very quickly after they mate and it's hard to rush them back to the studio.

This mayfly was collected from the Neversink River on September 8th, 2006 and added to Troutnut.com on October 4th, 2006.

Trico shuck
Posted by Martinlf on Jul 22, 2016
Catching some fish on duns one early morning I pulled a cripple from the drift and noticed that the shuck looked cream colored to me. Has anyone else noticed this?

These Tricos are found on most reservoirs in the Great Basin. They come off the water late in the afternoon and early evening. They pull out of their subimago shuck on any object, cars, shirt sleeves, eye glasses, or rocks. They appear as clouds on most reservoirs and stimulate an Alfred Hitchcock-like feeding frenzy with the fish. They are short lived but what an impact. This hatch lasts for several weeks here in the Great Basin.
A good spent wing example can be found at Just2ty4.com.
