Subimago

The final moult of the naiad is not to the full adult form, but to a winged subimago that physically resembles the adult, but which is usually sexually immature. The subimagos are generally poor fliers, and typically lack the colouration patterns used to attract mates. The subimago eventually moults to the full adult, making mayflies the only insects where a winged form undergoes moulting. Like the adult, the subimago stage does not last for long, rarely for more than 24 hours. In some species, it may last for just a few minutes, while the mayflies in the family Palingeniidae have sexually mature subimagos and no true adult form at all.
