This dun hatched out from a nymph in my aquarium on July 16th, after being collected July 10th. It is probably of the same species as this nymph, and this dun which also hatched from one of these seemingly identical nymphs.This mayfly was collected from Nome Creek on July 10th, 2011 and added to Troutnut.com on July 16th, 2011.
