The state in some insects between the larva and the imago is known as what?
Pupa Pupa A pupa (, "doll"; plural: "pūpae") is the life stage of some insects undergoing transformation between immature and mature stages. The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis, with four life stages: egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The pupae of different groups of insects have different names such as "chrysalis" for the pupae of butterflies and "tumbler" for those of the mosquito family. Pupae may further be enclosed in other
Imago 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 imago often is referred to as the adult stage. Members of the order Ephemeroptera (mayflies) do not have a pupal stage, but they briefly pass through an extra winged stage called the subimago. Insects at this stage have functional wings but are not yet sexually mature. The Latin plural of "imago" is "imagines", and this is the term generally used by entomologists – however, "imagoes" is also acceptable. "Imago" is Latin
