Translation:I am not a child, but I do not like spiders!
The only age ranges seem to be: bebo (probably up to preschool) paŝetanto (toddler) infano (apparently up to pubescence) junulo (general catch-all term) and adoleskanto (teenager). I've also seen "antaŭ-junulo" which might translate to "pre-youth" but I'm not sure how commonly understood, or used that one might be. (what DO they mean by pre-young, anyhoo?)
There may be more exact terms for young people's age ranges but I haven't seen them yet.
What age range is adoleskanto? I know it can differ from language to language. In German law it's ages 14-17 (at 18 you're technically an adult), but in everyday language it can very depending on where you live. In many languages/cultures it's either 13-19 or 11-19 or whatever arbitrary number. Is there a consensus at all or are there competing interpretations?
