MAYFLIES or shadflies are a group
of insects constituting the order
Ephemeroptera. In the young or
nymphal stages, they live in the water of
ponds, lakes, or streams, where they can be
found under rocks or logs, in the mud at the
bottom, or occasionally swimming about.
When the nymphs are full grown, they come
to the surface of the water and transform
into free-flying aerial insects. As such, they are familiar to many fishermen and nature lovers. There are over 550 different species of mayflies known for North America north of Mexico. This report includes 48 genera and 222 species, with Illinois records of 126 species, 15 of which are described as new.
