Communal Beetle Larvae?

[NathanB]

Hi all, assuming the enclosure size, substrate quality, and diet is perfectly fine, which species can be kept as a colony? I currently keep a small group of Chlorocala conjux which were together for months as larvae and got along fine. I love to keep and breed communal species, so which other beetle species can be kept like this? I heard most flower beetles, any rhinoceros beetles or stags at all?

For some more interest, here's some of my Chlorocala conjux!

Pachnoda sp are generally safe to keep together as larvae.
