Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

Dorsal view of a Holocentropus (Polycentropodidae) Caddisfly Larva from the Yakima River in Washington

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

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.

Aurora August 31 to September 1, 2013

By Troutnut on August 31st, 2013

My dad and brother flew in to Fairbanks for a visit last night, and had the good luck to catch the second best display of aurora I've seen in six years in Alaska. The pictures don't do justice to the way these beams shot and shimmered across the sky, but they still show that my visitors had incredibly lucky timing. These pictures were taken just a few miles outside Fairbanks.

WOOOOOOOOOOOOOOOOOOOOOOOW!!!!!!!!!!!!!!!!!

Sure a photo does not do it justice because of the ever-shimmering constant movement...but those sure are some COOL photos anyway!!!

Funny thing you posted this today, Jason - I just had a dream about seeing the Aurora last night! Haven't seen them in a while myself, looking forward to catching one here again eventually.

Thanks for sharing, those are amazing pics!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
