Locust Breeding

Can anyone point me to any concrete evidence of how the Locust actually repopulate their numbers?

I vaguely remember a quote in one of the books (Aspho Fields, I think it was) and there’s that Cliffy B interview… but I can’t find either of them atm.

Does anyone know of how they did it?

As far as I know, it’s never concretely stated in-setting how they repopulate their numbers… it’s only ever done by paratextual word of god.
