While sitting behind the vise last night it occurred to me that since I have started tying entemology is becoming a bit more important. I've never really thought of nymphs as having different colors. Usually I'll tie on a hares ear or pheasant tail and call it a day. So anyway, I was sitting there and began wondering about caddis colors and then went on to wonder about mayfly nymph colors. As we all know the duns have defined colors on them and they sometimes change when they become spinners. Caddis also have definate color differences. How about nymphs? Do the different mayfly nymphs have a major difference in color over say light and dark. Will a sulphur nymph be yellow or an olive nymph be, well, olive? And while I'm bugging you for more information, what colors do you typically tie your caddis pupa in?
