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.

This is the second most common East-Midwest Drunella species, but it is not very important compared to Drunella lata. Ernest Schwiebert had this to say about their hatches:

An imitation is rarely required, but notes show that when it is needed it is needed badly.
