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.

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.

These won't really fit in the regular site sections so I figured I'd post them here.
I just took some neat pictures of the aurora from my window and out on my driveway. Normally I can't see aurora very well from my house because I'm right in Fairbanks where there's a lot of ambient light from town, but they were really bright tonight.
Previously when I've seen the aurora, it's been pretty neat, with colorful bands arching across the sky and shifting with barely perceivable motion. Tonight it was an amazing light show, especially for about 5 minutes around midnight, with bright red and green bands rippling across most of the sky at high speed. The pictures I got really don't do them justice, because my long exposure blurred out a lot of the detail, but they're still neat.
While I'm at it, I'll include some pictures I took around campus during the lunar eclipse a couple weeks ago.

Wow! First you make us all jealous with fish stories, then this. Do they need any English teachers up your way?

The night sky in the last picture is unreal.
Thanks

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.
