The Hendrickson mayfly (Ephemerlla subvaria) is a pretty big deal in the East and is one of the first reliable, fishable hatches early season. I like to carry both traditional hackled versions and patterns that sit flush in the film like Sparkle Duns, Comparaduns and Thorax style patterns. The "Hendrickson" patterns originally tied with the pinkish "urine stained fox underbelly fur" imitate the light bodied female and the darker brown bodied male is imitated by patterns like the Red Quill.
