Apito/Chronology

Demon Lord Attack Arc
While strolling through the Great Jura Forest, Rimuru had stumbled upon Apito and Zegion, with the two of them heavily injured. At first, Zegion didn't want Rimuru coming any closer, but Rimuru managed to convince them to let him help them. The two end up being rescued by Rimuru when he shared some of his Slime cells and had also been given names.

Apito then started her honey gathering duty for Rimuru.

The Octagram Soars Brightly Arc
Apito and Zegion were still in the insect form, but they managed to become much stronger than before.
