This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

These were collected during the spring and summer from Mill Creek, a tributary of Dry Creek and the Russian River. They were collected from areas with a moderate flow and a gravel and cobble base. There was little filamentous algae but good growths of diatoms.

The larvae and pupae are 6-7 mm. The cases are 8 mm.

The larvae were identified using Merritt, Cummins and Berg (2008). The pupae were identified to family using the above.

Nice Matt. Interesting thing about some Apatania I seem to recall that in some places females greatly out number males and there is parthenogenesis.
