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.

I fished for a few hours this morning to wrap up a visit to the DC area(used to be home). I am now back in PA, but my thoughts remain at Big Hunting Creek in MD. I approached the first pool from downstream and immediatly began casting to holding fish. This was my first time on the small, clear stream, and little did I know, these Native fish are spooky. I was amazed at the numbers of fish here, 30-40 fish in this particular pool. Needless to say, I blew it after missing 3 strikes and putting down the entire pool of fish. I hopped in the car and headed upstream. Here I found a nice pool and hooked one fish on a big #10 Adams. I said they're spooky, I never said they were picky.



After a few more casts, this pool was done. I then decide that I have been gone long enough from the first pool for the fish to be working again. I head back to the pool with a new plan. I walk along the path about 100 yrds. downstream of the pool and cross. I then walk until I am at the tail of the pool. Here I crouch behind a big boulder and watch the fish. After a minute I notice that most of the fish are woking the left bank feeding under an overhanging bush. These fish are taking beetles and ants. I wait for the fish to get going and lay down a few casts to the middle, with the intentions of moving each cast an inch or two further left than the last. I get hung up in a tree behind me a few times, but eventually it all comes together. I manage a few nice Brook Trout on the #10 Adams.





The action tapers off as these Native fish begin to catch on. On my way out, I hit up a deep plung pool where I raise a nice Brown Trout to my Adams



I can't think of a better way to leave town. My first trip on Big Hunting was both humbling and rewarding.

Send me a PM if you ever consider going there. You guys have some incredible trout fishing in your area.
