The small streams that empty into the Moormans in Sugar Hollow are all first order/headwater streams, and many of the insects that we find there are only found in such streams. I've highlighted in Bold no less than 27 EPT species that I've seen in these streams and nowhere else. I have no doubt whatsoever that we will find additional unique taxa in these clean, crystal clear waters that cascade down the mountains into this valley. I fault myself for not moving out to explore even more streams in the Blue Ridge.
These streams are especially rich in caddisfly larvae, freeliving caddisfly larvae (Rhyacophilids) and the Uenoids -- the "little northern casemakers." We've identified 4 of the Rhyacophilids so far, but we've found at least 2 other species on which more work needs to be done. You may recall that the Appalachian mountains are the best place in the world to look for Rhyacophilids.
Also worth noting, I've only found 2 small minnow mayfies in these waters so far, most common, the very intolerant (1.5) Baetis tricaudatus. This is a "mountains only" small minnow mayfly which I've also found at the Rapidan River and South River up in Greene county.
