Instar
The developmental stage of larval or nymphal insects between molts.
Larva
The growth stage where the insect eats and increases in size, shedding its skin multiple times.
Eclosion
The emergence of an adult insect from the pupal case, or a larval insect hatching from the egg.
Hemimetabolous
A type of metamorphosis with three stages: egg, nymph, and adult, undergoing gradual development.
Adult
The final stage of the lifecycle where the insect is fully developed and capable of reproduction.
Molting
The process of shedding the exoskeleton to allow for growth in immature insects.
Pupa
A transitional stage where the insect undergoes metamorphosis and reorganizes into an adult form.
Metamorphosis
A significant change in form from one stage to the next during the insect's lifecycle.
Voltinism
A term that describes the number of generations an insect species produces per year.
Egg
The initial stage of the lifecycle where an insect begins development.
Diapause
A period of suspended development and reduced metabolic activity, allowing insects to survive adverse conditions.
Oviposition
The act of laying eggs by the female insect, usually in locations suitable for larva development.
Imaginal discs
Groups of cells in larvae that will develop into the tissues and organs of the adult insect during metamorphosis.
Nymph
A stage in the lifecycle of hemimetabolous insects, resembling a small adult and molting until maturation.
Holometabolous
A type of metamorphosis with four distinct stages: egg, larva, pupa, and adult.
