Some Metamorposis Types
  • anamorphosis metamorphosis in which the
    immature stages have fewer abdominal segments
    that the adults
  • epimorphosis metamorphosis in which all of the
    segments are differentiated in the embryo before
    hatching
  • complete development in which there is a pupal
    stage ( holometabolous)
  • incomplete (or simple) development in which
    there is no pupal stage
  • ametabolous without metamorphosis
    characteristic of primitively wingless insects
    that emerge from the egg in essentially adult
    form except for the size and development of the
    genitalia
  • paurometabolous metamorphosis without a pupal
    stage and with terrestrial immatures that closely
    resemble the adult in general body form (
    gradual metamorphosis)
  • hemimetabolous metamorphosis without a pupal
    stage, but with aquatic immatures that differ
    significantly in body form from the adult
