Imago
From Wikipedia, the free encyclopedia
In biology, the imago is the last stage of development of an insect, after the last ecdysis of an incomplete metamorphosis, or after emergence from the pupae where the metamorphosis is complete. As this is the only stage that is sexually mature and has functional wings in winged species, the imago is often referred to as the adult stage.
The Latin plural of imago is imagines, and this is the term generally used by entomologists - however, imagos is also acceptable.
