Byron, I consider it an adult, but as I said I do tie some with a shuck as an x-caddis and a few with a bright green stub of z-lon. Kind of a universal place to start. So until I add the shuck, it then becomes an emerger/cripple, or egg sack an egg layer. Just want to make it clear the Neff caddis has been around for a long time, other than Leiser and Solomon's book it wasn't written up to my knowledge. It probably was but I never heard or read about it until the book came out. When Leiser owned the Rivergate fly shop he had a card set up with different caddis colored dubbing and assorted deerhair. That takes me back a few years.
