[46] [47] Traver contributed to the 1935 work The Biology of Mayflies, [48] and has been called "the first Ephemeroptera specialist in North America". [49] As of 2012, over 3,000 species of mayfly in 42 families and over 400 genera are known worldwide, [50] [51] including about 630 species in North America. [52]
Baetidae is a family of mayflies with about 1000 described species in 110 genera distributed worldwide. [1] These are among the smallest of mayflies, adults rarely exceeding 10 mm in length excluding the two long slender tails and sometimes much smaller, and members of the family are often referred to as small mayflies or small minnow mayflies.
Hexagenia limbata. (Serville, 1829) [1] Hexagenia limbata, the giant mayfly, is a species of mayfly in the family Ephemeridae.

Tomah mayfly nymphs and sub-adults feed predaceously on other invertebrates in the floodplains, which is unusual as other species of mayflies feed on dead plant material. [4] Siphlonisca is a monotypic genus, meaning Siphlonisca aerodromia is the only species within this genus. [7] The species is univoltine, meaning one generation is produced ...
Only about 200 of those 450 species live in Ohio all summer, which means the rest follow a flight plan that takes them through the state into Canada. ... Ohio may only be a tiny blip on the map ...

Out of all the mayfly species in the family Ephemeridae, they are the most common in North America. [3] The nymphs of the species burrow and can be found the same time as the Green Drake (Ephemera guttulata) mayflies, which the species acts similar to; if one trout stream has a hatch of E. simulans, there might also be a hatch of E. guttulata.
