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.

I spent more than an hour casting to several rising trout in this pool and caught only two. Its clear water and tricky currents harbor dozens of free-rising, usually very hard-to-catch fish.

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

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.

2 large greenish bugs from kick sample last weekend.

River Derwent, Derbyshire, UK.

Someone said they might be crane fly larvae?

The one on the left looks like a crane fly larva, Tipulidae. The one on the right looks like a snipe fly larva, Athericidae.
