Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly Nymph Pictures

 This pretty Ephemerella nymph has really weird markings. It has one band on the tibiae (

and a thin but distinct dorsal (Dorsal: Top.) stripe faded in the center which looks very different from the stripes on Ephemerella needhami and Ephemerella aurivillii. It definitely has the fan tail characteristic of the Ephemerella genus.


This mayfly was collected from unknown on February 7th, 2004 and added to Troutnut.com on January 25th, 2006.
