Ephemerella invaria (Sulphur) Mayfly Nymph Pictures

OK, the invaria nymph shows the same lighter darker dorsal bandsand the solid dark ventral color on the abdomen as the subvaria, though its size makes me wonder if it is immature and may darken. For many considering this kind of detail will be superfluous, but for some of us nuts who like to fritter away the hours considering the possible uses of such information, this may confirm the claims of those who like to leave streaks in when blending fur, or perhaps even the claims of Caucci and Nastasi who promote a spectrumized dubbing.
