Its abundance is unknown. The Tomah mayfly is the only species within the monotypic genus Siphlonisca. [2] The Tomah mayfly is a habitat specialist and an indicator species. [3] Adults only live for a few days as they deposit eggs into rivers and streams. [4] Nymphs hatch from eggs and migrate to the floodplains during springtime and following ...
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.
The 2014 hatch of the large black-brown mayfly Hexagenia bilineata on the Mississippi River in the US was imaged on weather radar; the swarm flew up to 760 m (2,500 feet) above the ground near La Crosse, Wisconsin, creating a radar signature that resembled a "significant rain storm", and the mass of dead insects covering roads, cars and ...
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 ...

Mayflies are commonly used as models for fly fishing lures. Both the nymphs and the adults are common food among the aquatic stream world. With their long tails, they are very attractive bait for many species of trout, and in some cases small mouth bass.
The nymphs of E. vulgata burrow into the sediment at the bottom of ponds. Most burrowing mayfly nymphs use the gills on their abdomens to create a current of water through their burrows, thereby ensuring sufficient oxygen is available to absorb through the tracheae in their skin.
