Thanks! Yes, going underground will prevent desiccation. Just wondering if 84 F is just too hot even if they are hydrated...Orin's book has a little info about a few species but I do not believe any info is offering for this species. I have noticed this species is active at 64 F and 84 F so that is nice and I am assuming is indicative of their hardness. I would define this species as very hardy as I have not lost one baby or juvenile yet. I have flame legs and Thailand Rainbows die all the time. I am moving away from owning millipede species I can't breed. Have not "smelled" any dead yet. I know they can die and you cannot always smell them but I usually can.I try not to let my place get warmer than 80F. I think there were a few days at 82 when the AC was dying. I assume pedes go underground if it gets too hot, which should provide some insulation as well as prevent desiccation.
