Thereus (mythology)
''Thereus'' is a genus of gossamer-winged butterflies (family (biology), family Lycaenidae). Among these, it belongs belong to the tribe (biology), tribe Eumaeini of the subfamily Theclinae. These small butterflies occur essentially all over the Neotropics.See references in Savela (2011) Classification Though this genus was first proposed long ago, for much of the time ''Thereus'' was included in the "wastebin genus" ''Thecla (butterfly), Thecla''. However, the two genera are not particularly close relatives among their subfamily. In recent times, it has been proposed to remove several species from ''Thereus'' to smaller or even monotypic genera. While this might be warranted in some cases, it is not followed here pending more thorough study. The junior synonyms of ''Thereus'' are thus: * ''Molus'' Hübner, [1819] * ''Noreena'' K.Johnson, MacPherson & Ingraham, 1986 * ''Pedusa'' D'Abrera, 2001 (may be ''nomen nudum'') * ''Solanorum'' Johnson, 1992 * ''Timokla'' Johnson, Kruse ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...
