Thought some folks might be interested in these photos of Anafroptilum bifurcatum nymphs. They're abundant in the Russian River from mid March until mid June and again from mid July until September. They're usually found in slow water along the edges of glides and riffles. Subimagines usually emerge from early afternoon until early evening. Adults usually show up in the late afternoon or early evening. males congregate in swarms along the edge of gravel bars and females are usually seen flying over fast glides or riffles laying eggs. Mature nymphs are 5-6 mm long (not including cerci).

Luke -

Glad you enjoyed the pictures. I like these little animals but it's always a challenge to get a good photo of them between their size and their tendency to move just about the time you get the focus zeroed in.

Great pictures, Mark. They look like miniature versions of Ameletus nymphs. I've had good luck with little Sawyer PT's using mallard flank touched up with a marker instead of pheasant tail barbules. The Oliver Edwards style of baetid nymph works great too. On Fall River they can be pretty effective from mid Summer on.

Kurt - Yeah, they do look like miniature versions of Ameletus. Or at least have some of the same mannerisms and elegant coloration. Always amazes me how the colors don't really show until you get a photo or look at them under a microscope (or maybe they do if you have better eyes than mine).

When I get them in the field they look like little camouflaged specks at first, especially when they're sitting on some sand or gravel. Usually takes me a second to figure what I've got, but those banded cerci give them away pretty quickly.
