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.

I'm taking a road trip from Denver to Great Falls, MT next week, and I'm hoping to deviate from my course a bit to get some flyfishing in. Anyone know of a good hatch that would be on my route?

Too late for olives out west? Call some shops in the area; they'll know. Best luck; have a good trip.

First (can I go along) ha ha Second stop at wolf Creek below Holder Dam. Then fish down to Craig I have fished this water in Novmber Take along your shotgun for ducks and fish in the afternoon.You will need some Pink bead heads about 14 and if the sun is out some 16-18 Olives Drys with a few 16-20 Adams.That should do it have a great trip.

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.
