as the title says

I is short for instar. When an arthropod is first born, it's "first instar," or 1I. Each time it molts it gains an instar.

Birth < 1I < first molt < 2I < second molt < 3I etc.

This systems is more often used for arthropods that have a set number of instars before maturity, such as Lepidoptera larvae or scorpions. For arthropods that don't have a set number, such as spiders, this system is not used as much.

Some countries use L1, L2, etc. for "larval 1, larval 2 . . ."

instars.

for instance, a new born nymph would be 1st instar.
when it moults, it becomes 2nd instar.
and when it moults again, 3rd instar.


I belive a scorpion usually has 6-8 moults before maturity, but it depends on the species. once a scorpion hits maturiy it will not moult again.
