Well, I have spent the last 3 days on Silver creek and other than seeing baetis every day, each of the last three days has been completely different.  Three days ago I saw MANY mahogany duns and the last two days I only saw a handful.  The fish still recognize them but not all of the risers are willing to eat them.  Today, as it was windy early, hoppers worked quite well and the two prior days they didn't seem to garner much attention.  Tomorrow the wind is supposed to BLOW.  Gusts to 28 mph.  We'll see...

Here are two October Caddis images from yesterday on Silver Creek:
