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.

Had a great week pinning, caught many trout every day. Am glad I moved to this area of PA! Lots of trout are eager to eat my baits. Limited out every day and have a couple dozen 12" - 18" browns in my freezer.

Glad for your success, Cdcaddis18, and welcome to the forum. Also, welcome to the area - I am also a transplant here from upstate NY. I would only suggest that you fill your freezer with smaller fish and leave the bigger ones to fight (and spawn) another day. A little digital camera would nicely preserve the memory of the larger ones without cluttering up your freezer. If the streams you fished are indeed well known, then the fish you caught had probably been caught and released many times by other anglers for the future enjoyment of others, in this case you. Try to be mindful that most streams here in Central PA are pretty heavily pressured, and that your fishing would likely not have been nearly as successful on this outing if every angler before you had limited out on big fish.

Pinning is a very deadly method to present natural bait or nymphs to trout. Skillful pinners can easily decimate fertile trout streams.

Westbranch, I hope you and Shawn can prevail on this guy to release his fish before they are all gone!
