Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

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.

I was fishing from my dock the other day to a school of stocked rainbows (I think) and I finally managed to get one of the buggers. For stocked fish, they're being awful difficult to catch this year. Last year I'd get plenty with a Panther Martin, but they won't even go for that this year!

Anyway so I got the trout in, and I couldn't figure out what exactly it was. The markings were more like that of a brown, but along the top of the fish and a little on the bottom it was emerald green. Also in the middle where the pink stripe usually is on rainbows it was a sort of pale gray-ish.

There's Atlantic Salmon in the lake as well, could it have been one of those buggers? I'm totally lost.

...maybe it was just a little seasick!
