*Drunella coloradensis

This common name refers to only one species.

Mayfly Species Drunella coloradensis

These are very rarely called Autumn Green Drakes.
This species is very similar to Drunella flavilinea. In areas where their ranges overlap, they can sometimes be found in the same streams. Allen and Edmunds (1962) say that Drunella coloradensis tends to favor colder water than Drunella flavilinea and that it may emerge as much as a month later.
