Ephemerella aurivillii Mayfly Nymph Pictures



 This specimen seems to be morphologically identical to the darker specimens of its species, but it's a very distinctly different color. I'm guessing this is a gender difference, just as I've guessed for the similar E. subvaria nymphs.

This mayfly was collected from unknown on February 5th, 2004 and added to Troutnut.com on January 25th, 2006.
