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.
