Just an enthusiastic amateur.

They're mayfly (Baetidae) nymphs. The common name is Blue Winged Olives.

Both Fallceon thermophilos and the unidentified species were collected in the Russian River. Both were found in fast water with a gravel substrate. They range in size from 5-6 mm for mature nymphs. Fallceon thermophilos male Fallceon thermophilos male Fallceon thermophilos female...
