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.

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.

Beautiful wild fish, missed at least three strikes by this one the previous trip here, got it on the first cast with a #10 modified Joe's Hopper - and fought way hard for it's size!
Joe-Pye-weed, boneset, and goldenrod
Virgin's Bower is in full bloom right now (another shot for Spence & his better half!)  ;oD

The "Five-Hole" (hockey pun intended...) - first time I fished this pool, I caught five trout!  Brookies, browns, and rainbows have all hit my dry flies in this nice little spot.
Bedstraw (Galium species) on riverbank
Glowing in the sunset...
Cardinal flower (Lobelia cardinalis)
Spotted jewelweed (Impatiens capensis)
Field mint (Mentha arvensis) - this plant makes the best mint tea in the known Universe!  Pick fresh leaves, steep in boiled water for 5-10 minutes, add sugar as desired, and enjoy!
The first "Rearing Pond" - an obviously artificially deep hole that was supposedly dug out for rearing trout - the rest of the stream is ankle-to-knee deep with occasional areas that get waist to maybe chest deep...but this goes over my head, I know because I took a swim!!!
Blue vervain (Verbena hastata) - for Paul!  ;oD
One more shot of that little wild rainbow...

Just had to post a few more pics of the Pine, this time from both the Buhl Dam section and the Rearing Pond Road area. Even though the fish have been running small, the scenery has been just spectacular as of late with the mass blooming of wetland wildflowers along the banks. Threw in a couple of pics of a wild little (9") rainbow too just to show you what the fish look like, though a photo never does a fish justice, especially in the glowing light of the sunset. Enjoy!

P.S. Fish were hitting that modified #10 Joe's Hopper like mad until sundown...
No matter how big the one you just caught is, there's always a bigger one out there somewhere...
