How do Zophobas morio pupate in nature?

[Acro]

It seems that Zophobas morio, in culture, are often separated into small containers to get them to pupate individually.  How does this take place in nature?  How does this take place in big feeder insect breeding operations?  I can't see them separating each larvae from thousands of others.

Like most darklings they hollow out a chamber under ground. There's no effort involved in placing them in solo cups and waiting.

For hobbyist raising a few supreworms, sure, hardly any effort.  But for huge feeder breeding farms, how do they do it?  I can't see them separating out thousands of thousands of superworms into solo cups.

That would take a few hours a few times a year, not much of an undertaking.
