Thanks to all who replied to my query. The fold up seine that attaches to a net is a great idea. I don't carry my net but rarely, but can see purchasing the seine.

As for what the guides said: One, agreed w/me that it was likely a baetis, and the other two said that without question it was a midge. All three fish the big Rio Grandeexclusively andmy question referred to a sm. feeder stream they probably are not well acquainted with. That did not give them pause in giving me their opinion, however.

I did see a few BWOs (3 or four) over the last four outings (I go daily) and the trout continue to love the tiny mayfly nymph flies I'm throwing. Had first fish of the day, a Bow, take me running down the bank. Only 15 inches but didn't want to horse on 6 X. 12 brought to hand today, and released. Great time ofthe year with stream to myself.
