What are characteristics of Ephemeroptera?

Ephemeroptera are aquatic insects that often go through many nymph stages (living in water) and two flying stages (the subimago and the imago). They are the only insects to have two flying stages, and can be recognized by their three caudal filaments (tails) at the tip of the abdomen, and a single claw on each leg.

Why do mayflies lay their eggs on dry asphalts roads?

Why do mayflies lay their eggs “en masse” on dry asphalts roads? Water-immitating polarized light reflected from asphalt attracts Ephemeroptera. J. Exp. Biol. 1998;201:2273–2286.

How are mayflies adapted to their environment?

The species are adapted to many habitats ranging from warm standing waters and coastal waterholes to the melted snow of subalpine areas. Atalophlebia species contains all the common large mayflies, most with a wingspan of up to 25 millimetres.
