Instar
An instar (/ˈɪnstɑːr/ (
For most insect species, an instar is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms of hemimetabolous (incomplete metamorphism) insects, but an instar can be any developmental stage including pupa or imago (the adult, which does not moult in insects).
The number of instars an insect undergoes depends on the species and the environmental conditions. Lower temperatures and lower humidity often slow the rate of development- an example is seen in the tobacco budworm.[3]
