General information about ages:
Depends on a general insects' lifespan, different insects have variant age of becoming "adults". For example, ladybugs and regular bugs live for 1 up to 2 years (3 years is also possible), so Miika and Roon can reach a pensionable age. However, insects like aphids or bumble-bees live only several months, so their age will be "frozen" in particular period of time when an insect reaches "twenty years old". Such insects would die not from being old, but because of a sudden stroke or losing life power. That is why Nail, PanPan, Firo and any other characters arrive at the age of "twenty" and freeze in the appearance loop without age progressing until the death.
