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 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.

Several years ago, while traveling along the trans-Canadian highway, I had a delightfully disgusting food item for which I cannot recall the name. I hope someone out there can think of it. I vaguely remember that it had fried potatoes of some kind that were covered with a gravy and a cheese. I am hoping that someone on a fly fishing adventure stopped in a road house once and had this fare. Jason, my apologies for insulting the sensibilities of some. I've been trying to think of this for over a year. Even my wife, who spent years in Michigan's Upper Peninsula, cannot name this treat.

POUTINE! Now I can rest in peace.

I suppose Hexagenia could be served in a similar way. It might even rival the calorie content.

Poutine, huh?

Sounds a lot like what we used to call Coronary on a Plate, which was scrambled eggs studded with big chucks of fried taters and patty sausage and covered with about a quarter inch of cheddar cheese.

It was delicious and I'll bet this Poutine is as well...
