Like most common names, "Olive Dun" can refer to more than one taxon. They're previewed below, along with 1 specimen. For more detail click through to the scientific names.

Mayfly Species Attenella attenuata

These are very rarely called Olive Duns.
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.

Mayfly Species Drunella walkeri

These are very rarely called Olive Duns.
Ernest Schwiebert had this to say about the hatches of this chunky Eastern Drunella (Blue-Winged Olive) species:

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