Habitat:

restored Indiana prairie with marshy wetlands

Thanks for pointing me in the right direction beallburton. There is a mayfly with the common name pale morning dun but it doesn't occur in the eastern US.

As a fly-fisherman, I'd match that mayfly with a pattern called a PMD (pale morning dun). What that means in terms of his scientific name, I don't know.
