The oldest previous blog post that I could find on trico spinners was dated 01/15/2012. I reread it with interest, and it captures my earliest days of fly fishing using trico spinners. The place where I encounter tricos in Colorado the most consistently is on the South Platte River in Eleven Mile Canyon, although I have not experienced this phenomenon in recent years. Nevertheless, I like to have some on hand just in case.
My 01/15/2012 post cites the usage of gray sculpin wool for the wing, but I have since reverted to white antron wings. I am not sure why. The change probably relates to the long amount of time that elapsed between tying trico spinners. I like the look of the crinkly white antron wing quite a bit. Hopefully I will get an opportunity to test some out in 2026. The trick is to be in the right place at the right time.
I counted my trico spinners and determined that I was adequately supplied, so I did not spin out any additional imitations. I will hope for a trico spinner fall in 2026.
