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.

Had a great trip to the Erie creeks Monday through Wednesday. My buddy and I had the best fishing in three years with plenty of eager anjd aggressive fresh fish and low numbers of other anglers. I won't tell you how many we hooked in three days because I know it is pretty hard to believe. I'm having trouble getting my pictures to come on larger than postage stamp size so if anyone would like to see a few pictures PM me with your email address or friend me at Facebook and in a few days I'll have posted up some of the pictures.

Nice, you think they're coming in a little earlier this year?

Most people that live here do not fish for steelhead and those that do usually release what they catch. I've had them (steelhead) actually swim up to me...usually its because they have a hook in their gullet. If you insist on fishing for them, use artificial flies or rubber salmon eggs (Burl's nuggets)...it make releasing them lots easier and they will usually survive. We (Co-ops) stock lots of brown trout these days in addition to steelhead smolts in Lake Erie tribs. The browns tend to travel in packs...where you see one, there are usually many others.
Fooling them is not easy...they tend to hit better under low light conditions. They attain large sizes here and 12-15 lb. browns are occasionally seen and caught. A Serbian immigrant caught a 20 lb. brown on July 4 at Walnut creek some years ago and it is displayed at Poor Richards Tackle.

My favorite trout stream picture; below, shows what a first class trout river looks like. The lack of stream gradient means that this river is not subject to the roaring scouring floods so common here in PA. that wipe out everything in the river.

"after you've caught thousands, the allure wears off."

Maybe that is how you feel but not me. I've caught many thousands of trout in the last fifty-two years and the allure and excitement is as fresh today as it was when I caught my first trout on a fly when I was seventeen years old. I've only caught a few hundred steelhead so I have a long way to go before I tire of them.

Nice Matt! That is a beautiful, healthy looking fish.
