I believe this is E. dorothea because of the small size- about 5 mm.

Description

Large size (maybe 3/4" or more), brownish body. Eyes and genitalia match the description of Hexagenia imagoes by Edmunds in Mayflies of North and Central America. Except for one dun with a yellowish body w/brown markings and yellowish veined wings, all specimens seen (a couple dozen or so) were spinners with brownish bodies.

Description from Wikipedia

Mayflies or shadflies are insects belonging to the order Ephemeroptera (from the Greek εφήμερος, ephemeros = "short-lived" (literally "lasting a day" "daily" or "day-long"), and πτερόν, pteron = "wing", referring to the brief lifespan of adults). They have been placed into an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies.
