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.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

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...
