A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
Two Schistocerca gregaria nymphs beside an adult. In biology, a nymph (from Ancient Greek νύμφα nūmphē meaning "bride") is the juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. [1]
Imperial moth (Eacles imperialis) development from egg to pupa, showing all the different instarsAn instar (/ ˈ ɪ n s t ɑːr / ⓘ, from the Latin īnstar 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs between each moult (ecdysis) until sexual maturity is reached.

Life-cycle of butterfly, undergoing complete metamorphosis from egg through caterpillar larvae to pupa and adult. Holometabolism, or complete metamorphosis, is where the insect changes in four stages, an egg or embryo, a larva, a pupa and the adult or imago. In these species, an egg hatches to produce a larva, which is generally worm-like in form.
Beetles are members of the superorder Holometabola, and accordingly most of them undergo complete metamorphosis. The typical form of metamorphosis in beetles passes through four main stages: the egg, the larva, the pupa, and the imago or adult. [83] The larvae are commonly called grubs and the pupa sometimes is called the chrysalis.
(The Center Square) – Pennsylvania’s incumbent U.S. senator just isn’t ready to let go. Bob Casey Jr., denied a third term in Washington by voters exactly a week ago, still hasn’t conceded ...
Hemimetabolism or hemimetaboly, also called partial metamorphosis and paurometabolism, [1] is the mode of development of certain insects that includes three distinct stages: the egg, nymph, and the adult stage, or imago. These groups go through gradual changes; there is no pupal stage.
