instar
Quick Summary
An instar is a stage in the life cycle of an arthropod, such as an insect, that occurs between two successive molts. Arthropods have a rigid exoskeleton that they must shed to grow. This shedding process is called molting or ecdysis.12
After molting, the arthropod has a new, soft exoskeleton that hardens over time. The period between these molts is known as an instar. Arthropods typically go through several instars as they develop. The duration of each instar can vary, often becoming longer as the arthropod ages. Some arthropods stop molting once they reach sexual maturity, while others continue to molt throughout their lives.2

OdonataThe larval stage…a series of stages, or instars, molting at the end of each instar into similar, but larger and more developed, versions of themselves. Very soon after leaving the egg, the first instar (prolarva) sheds its cuticular sheath, releasing the tiny, spiderlike larva. Because it is aquatic, the larva differs markedly…

DipteraMolts and larval stages…number of larval stages, or instars, is six or seven in black flies (Simuliidae) and four in most other Nematocera. Along the second line of evolution of flies, Brachycera have from five to eight instars while the maggots of the most advanced flies (Cyclorrhapha) have only three. One or two…
