Binomial name. Hexagenia limbata. (Serville, 1829) [1] Hexagenia limbata, the giant mayfly, is a species of mayfly in the family Ephemeridae. It is native to North America where it is distributed widely near lakes and slow-moving rivers. [2] The larvae, known as nymphs, are aquatic and burrow in mud and the adult insects have brief lives.
Mayflies "hatch" (emerge as adults) from spring to autumn, not necessarily in May, in enormous numbers. Some hatches attract tourists.
