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.

This little pool in update New York is enjoyed by many tourists every day, and it still holds a few trout -- stockers mostly, but you can't complain about the setting!

Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph

Dorsal view of a Setvena wahkeena (Perlodidae) (Wahkeena Springfly) Stonefly Nymph from Mystery Creek #199 in Washington

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.

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 hadn't seen this piece of their Planet Earth series yet and I just turned it on, half-way through unfortunately. They have some truly amazing footage! I'm amazed by some of the closeup videography the do with aquatic insects... they get some really difficult shots. Wish I had those kinds of resources and time for this site!

Is this a new one, because I don't remember this from the original series (which was astounding, by the way). I know they're supposed to be coming out with some new stuff soon. These people get some of the most incredible footage ever captured.

I don't know how new it is, but this isn't the first run apparently. They're rerunning it again at 11pm here though, so you might want to check your channel and set it to record at whatever time the next rerun is on there.

I'm watching the rest of it now... there's some very cool aquatic insect stuff, although that section is brief. The whole show is amazing.
