The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

My question is about Ephemerella dorothea dorothea body color.

Om May 30th I was capturing in my seine yellow body E. dorothea.





The fishing was great by the way. :-)

Then in the same section of the river on June 10th, I was again capturing what to me is the same specie but the body color is definitely an olive color.



So has anyone noticed in the same section of river E. dorothea varying that much in body color, or as the hatch progresses the body colors vary?
