**Attenella attenuata

This name is used in parts of Wisconsin to describe species nearly identical in form and behavior to yellow "Sulphurs" like Ephemerella invaria, but with a distinct green color.


This common name refers to only one species.

Mayfly Species Attenella attenuata

These are sometimes called Booger Sulphurs.
This intriguing species has received a lot of attention in past angling books. Recent authors suspect that much of this credit was a case of mistaken identity, with Attenella attenuata receiving praise for the hatches of Drunella lata and Dannella simplex. Much of the credit was legitimate and accurate, but this species is no longer thought to be on par with its most popular cousins in Ephemerella and Drunella.

I have several specimens listed under this species, but I'm not positive the identification is correct.
