**Drunella flavilinea

This common name refers to only one species.

Mayfly Species Drunella flavilinea

These are sometimes called Dark Slate-Winged Olives.
The Flavs pick up about a week after the closely related but larger Western Green Drakes (Drunella grandis and Drunella doddsii) finish hatching on most Western waters.

Their hatches may be complemented by simultaneous hatches of two less prolific species, Drunella coloradensis and Drunella spinifera.
