Posts: 1Hello,
This may be a longshot, as the image was from my iPhone and I couldn't get very macro.

Fish were slamming these in Amethyst Basin of the Uintas this weekend.

I think this is a spinner because of the clear wings. Swarms became noticeable around 10 AM to noon. They were clinging all over my clothes. Saw plenty of spent ones flat in the water.

If anyone can help identify, I would really appreciate it!

I've also included a photo of the fish eating them!

My first guess would be some sort of Callibaetis?

I think it's a Callibaetis female but not sure of the species. Beautiful looking country and a nice trout too.

Hi Ndebarmore-

As Spence and Mark suggest, it's a Callibaetis female imago (spinner), probably C. ferrugineus hageni.
Best regards,

Welcome to the forum, Ndebarmore.

Beautiful lake, beautiful fish, beautiful fly! I'm jealous...:)

Definitely a female Callibaetis imago (Speckled Spinner). I agree with Taxon on the probability of the species.

Welcome Ndebarmore. Beautiful setting, great description of the Callibaetis emergence and like Entoman , I'm jealous...nice fish too, cool pattern of spots on that one! Quite a difference from where I've been lately, throwing beetles on PA spring creeks. Congrats!
