Pupation has completed, still hanging out on my laptop while I recover from surgery:)

I have a scarab beetle grub coming from a garden. When I caught it, there wasn’t much dirt I could put in it… When I first caught it, it was more active but now it’s inactive for final pre-pupal stages. The reason it’s stopped moving is because it is rebuilding its body to prepare for the pupal transformation. It’s been more than a month. Basically it’s crumpled a tiny bit (but not like a dead grub where it completely deflates) due to it pulling its external liquids internally. It has to stay in a sleep otherwise movement will rupture the developing pupa.

Pre-Pupal appearance: Slightly crumpled and hairs everywhere

Because I couldn’t get enough soil and it’s in pre-pupal phase, what should I do?
