Along the way...just couldn't resist taking some photos

I was on a mission this morning -- to check elevation and mileage at some of the local sites where I've been finding Uenoids.  I hope, in the near future, to sum up my findings on the Uenoids I've found over the winter: which species are found where?   And by the way, the season is pretty well over; pupation is underway.  I saw more cases this morning that were sealed up than those that were open for business.

But while I was out and about, I couldn't resist looking around.  Here are some of the photos I took.

Doyles River at Rt. 674.

1. The beautiful, fully mature, male Heterocloeon amplum small minnow mayfly in the photo above.  More views.

2. At the same site, a Perlodid stonefly, Diploperla duplicata.

3. And also at the same site, a Uenoid caddis, Neophylax oligius (pale stripe down the face).

Microscope view of the face.

Sugar Hollow, small, 1st order stream, elevation 1200 ft.

1. Uenoid caddisfly larva, Neophylax mitchelli.

2. Uenoid caddisfly larva, Neophylax aniqua.

N. aniqua larvae appear to be much smaller than N. mitchelli: 3 mm vs. 5-6 mm.  And I suspect that they're only found at high elevations in 1st order streams.

3. Ameletid mayfly, Ameletus lineatus.

4. And a Rolled-winged stonefly, Leuctridae, genus Leuctra.
