Scythris Sachkovi
''Scythris'' is a genus of gelechioid moths. It is the type genus of the flower moth family, which is sometimes included as a subfamily in the ''Xyloryctidae'', or together with these merged into the Oecophoridae. The genus was erected by Jacob Hübner in 1825. It is the largest genus of flower moths, and as such might not be fully monophyletic with regard to some very small or monotypic genera placed in the same family. In addition, new species of ''Scythris'' continue to be discovered and described.FE (2009), and see references in Savela (2008) Selected species Species groups The species of ''Scythris'' have been divided among several groups, which may or may not be monophyletic; those that are may – provided they are closely enough related to the type species '' S. limbella'' – be considered subgenera. There is a considerable number of species whose exact relationships are hitherto elusive. Some have been placed in a "Monospecific species group" of their own, ...

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 ...
