Salmonflies
Pteronarcys californica

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

This view of the pipeline, the Atigun River, and an impressive sunset/rise was one of my first views of the North Slope as I came through Atigun Pass in the middle of the night.

Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

Dorsal view of a Neoleptophlebia (Leptophlebiidae) Mayfly Nymph from the Yakima River in Washington

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.

Caught 2 fish on the West Branch on CDC and Elk in about a size 10 or 12. Both were the village idiots, for their jaws were ripped to shreds.

On the Beaverkill, drifted nymphs through fast water. Got one small brown, then broke off a very large fish on a big stonefly nymph. Then caught and landed a 17 inch brown on a stonefly nymph. His mouth was beat up too, and it had someone else's fly in it.

Not much insect activity, it was about 85 degrees and sunny. Some caddis on the West Branch and some big mayflies and stoneflies on the Beaver Kill.
