Female Penelomax septentrionalis Mayfly DunFemale Penelomax septentrionalis Mayfly Dun View 10 PicturesI'm confident this dun belongs to septentrionalis, because her legs are just too long for any other Ephemerellid, and her unusual mid-dorsal (Dorsal: Top.) stripe matches those of two easily identified nymphs I collected some miles downstream.

This really pretty mayfly was in kind of bad shape when I found it crippled on the surface, and bouncing around in my container with a bunch of green drakes didn't help.

Female Epeorus longimanus (Slate Brown Dun) Mayfly SpinnerFemale Epeorus longimanus (Slate Brown Dun) Mayfly Spinner View 1 PicturesI associated this female with a male I collected one night later. For a great and informative discussion of all Epeorus species and other mayflies be sure and read, WESTERN MAYFLY HATCHES by R. Hafele and D. Hughes. They rate all of the western mayflies and they rate the hatch of this genus a 25 out of a possible 45 points based on several rating criterion. They provide insect photos, possible fly patterns and fly presentations. This is a great book.
