I collected this male dun together with a female spinner, a female dun, and another male dun.

A few of these tiny stoneflies were among the only species of aquatic insect adults in the air on this particular afternoon, with most of the action coming from a species of Epeorus mayfly.

I collected this female dun together with a female spinner, a male dun, and a larger, damaged male dun.
