Here's an image I took today on Silver Creek of a baetis.  This baetis was/is tiny!  A #22 or #24.  Mahogany duns are also getting smaller, already.  The mahoganies I saw today were around a #18.  There were tons of baetis mid-day and the fish were on them.  Hoppers are still around and are still working.

I used spot metering and metered the baetis and dialed down the exposure compensation 1 stop.  Shot taken with the Nikon 105  2.8 lens.
