the resemblance of an adult individual to its juvenile form. Paedomorphosis is observed when the adult (imago) and juvenile forms exist under the same conditions. It especially characterizes animals with little capacity for movement. Organisms marked by paedomorphosis include the caterpillar-like female casebearers of the family Coleophoridae (although there is a pupal stage between the larval and imago stages) and the wingless females of the orders Embiodea and Grylloblattida. Paedomorphosis may be associated with neoteny.
