At what age does Mothra evolve into an adult?

[lanayasha]

I bought myself a Mothra for Christmas <3 Right now, I have the batora grub teen and I was just wondering if anyone knew at what age do they go into their cocoon form or become an adult? My little guy is 10 years old (really I've been running him for like a week or so; I had to put him to sleep a few times while I went out) and I thought surely he would have evolved by now!

Does anyone have any pointers?

Thanks <3

If I remember correctly it should enter in the adult stage at the age of 8 or 9....

I've run a mothra a few times now and mine have ranged from 7-9 days (some adults do take a bit longer I believe) and the average max life span (remember these aren't longlived tamas) for me ranges from 13-15 days .
