Lucanus elaphus pupation cell creation

[FlamingSwampert]

Hello everyone!

I have a confirmed pair of L3 lucanus elaphus from Insect Brothers, who I highly recommend for US native beetles! Mine have been hanging out at the bottom of their jars for awhile, and are alive and well. They have made a "peephole" on the side, so I can monitor them. How can I tell when their pupal cell has been constructed? Will the flake soil appear any different?

Thanks!

The flake soil would look wetter around the cell.
