According to Allen & Edmunds '63, both species are well distributed along the Appalachian corridor from the carolinas up into Northern Canada. As one would expect, emergence occurs later the further North you go. In the NE, a time frame of July to late August is given, depending on the year and location. Curiously, this older paper reverses the size description, showing serrata (sordida) as the smaller critter. The good news is it is consistent with other papers that list tail annulations as a diagnostic character and have it listed in its key.

I have fairly extensive experience with the virtually identical Serratella tibialis (Little Dk. Red Quill) out in my neck of the woods. Tibialis has since been relisted in the Ephemerella genus, but no matter. Still a dark little Summer ephemerellid, whatever scientists choose to call it. It is fairly common on some mountain streams and is probably the most important Summer mayfly we have on those lacking tricos and where the PMD's have long since finished. Unlike the Summer heptageniids that usually seem to trickle off, these hatches are more concentrated and they can come off in pretty good numbers. Pain in the butt to fish as they are usually very difficult to make out on sparkly Summer riffles and don't seem to show up in the evening air all that well, either. A lot of anglers miss them and assume the feeding fish are working caddis (that are always about) or terrestrials in the film. This is one hatch where the fish definitely seem to prefer flies with dark wings that match the natural. I rarely get away with bright sighter posts. It was much easier to fish them when I had younger eyes. :)

Yes, the fish also can be a bit picky about the wing color with Teloganopsis, at least on one pressured stream I fish. I've tied parachutes with colored posts then with a black marker darkened the lower portions, leaving just a bright tip, for those iron grey days when glare seems everywhere. Sometimes a solid black post or black burned wings will show up well enough, depending on the light.

"I just got back from the great white north. WOW 6 weeks in the bush."

Welcome back Mack! Sooooo...PHOTOS??

Funny thing, this here website got a little quiet for a while, so I started posting some of my local trips (especially with the wildflowers in full bloom). That seemed to have gotten the ball rolling, now we're getting some fresh trip reports replete with wonderful photos. Of course, we always know we can count on Spence for that... ;oD

So Mack, I know you got' em, post your latest adventures like the rest of us!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Mack, good for you! That sounds like a great time, I imagine your son is loving it too. Yeah, check out some of my latest posts, got caught up in June and July in a butterfly habitat survey project in the Manistee National Forest, have been making up for it with fishing in August and September...

Do post some pics, I would love to see you and your son at work in the wild.
