I don't normally take photos of this one since I took a lot of them early on. But, what a chubby! I used to work with a gal who called this larva "Michelin man" -- seems pretty fitting. Caddisfly larva, Rhyacophila fuscula. I'm seeing a lot of big ones at the moment.
And I believe I mentioned last time that I find quite a few Paragnetina immarginata at the Rapidan River. One of my photos is great for species ID. I'll add it later on if I can get this damn Photos software to work! (Hope my computer isn't on its last legs.)
Made the mistake of putting two in my tray at once, and I couldn't keep them apart.
And I found another Rhithrogena. This one was fully mature and given the spreading, rising wing pads, I'm pretty sure it was in the process of hatching.
Also found a few little Perlesta. I'll do some microscope work on this one and see how it compares to the nymphs I've found in other streams.
I'll edit this entry if I mange to annotate the picture I mentioned, pointing out the key features for species ID for Paragnetina immarginata.
Here we go. Beaty, "The Plecoptera of North Carolina," p. 18. "head M-pattern with medial pale line extended anteriorly, often connected to pale frontoclypeal margin; yellow femora distinctively patterned with dark brown longitudinal bar extending about 2-3 the length; abdominal terga banded, anterior half dark; anal gills absent."
