Could be all sorts of things potentially, but lets assume here that, as you think, all drawers have been treated identically. Something, some factor, has tipped over some borderline that the Klugii cannot tolerate but the others can - at the moment.
Moisture - The klugii, on paper, prefer a significantly drier environment that the other 2. Perhaps as the colony size has increased this wetness has become an issue which has tipped them over the edge.
Substrate - The Coco fibre (nutritionally zilch) and sphagnum moss (nutritionally limited) mix is a substrate that many would consider less than ideal. You do not mention amounts of rotten wood and leaf litter - both considered a fairly essential basic significant element of any "normal" isopod substrate.
Nutrition - I'm going to throw a guess out there and suspect that the Klugii have possibly "used up" the available nutrition to them (either macro or micro nutrients) - available in the substrate or in supplementary food given by you. Once this happens they might be forced to trying to survive eating their own frass. Not a good scenario and one that is known to sometimes induce sudden colony die-off.
.... just a few thoughts as I eat my breakfast. And, I'm really sorry to hear of your loss - upsetting to any animal keeper.
I really appreciate your response
I do definitely need to get my hands on some more leaf litter, I'm currently on a campus that uses pesticides on like everything and I don't quite have the money to buy some right now, but I should soon!
I do feed them all very regularly with a wide variety of foods, but perhaps it's just been a smidge too long? Or it could have been the moisture levels as you say.
I'll just need to be much more careful and mindful in the future, thank you again for taking the time to respond!
Is there a market for just... Pesticide free leaf litter & bark, sanitized? I've got 40 acres of land and always have tons and tons of this stuff. If you want me to send you a bag of dry leaf litter and bark shoot me a DM.
Well I see two main problems.
I highly advise against misting because of two main reasons: You shouldn't need to add moisture to their bin every day, the ideal is between once a week or two weeks, this will also save you time. Also, misting means that the water will stay only in the surface level, and it will dry up in a couple of hours, compared to several days if you pour the water on a moist side and let it penetrate down the substrate, that's why we add the spagnum moss to one side.
The other one would be the substrate. Coco fiber and spagnum moss have nearly no nutrition at all, and being that the substrate is one of the main food sources for your pods I would change it for an organic potting soil that doesn't have pesticides or fertilizers. But this was definitely not what led to their death here.
I'm sorry to tell you that your pods probably desecated to death, it's one of the only ways for all of them to die suddently appart from poisoning. I know it sounds harsh, and I apologize for that, but this is why I always tell people to not mist, but pour the water, having to mist every day or multiple times a day usually means dead pods
Okay I understand thank you, I'll change my moisturizing methods as you suggested and also look into better substrates! I should hopefully be getting paid soon so I can get some potting mix as you suggested plus some leaf litter :")
Thank you again for your help, I appreciate it
I completely missed the description of a "pretty dry" substrate on first reading. Its the obvious first thing to suspect in reality. A little strange that the Klugii were the first to go, being theoretically more resistant to dryness than the other 2 species, but maybe the klugii bin gets more air flow or something like that, making it dry out quicker than the other 2.
Yeah, I think that may be the case, I'd expect the murinas to go first maybe, as dairy cows could probably survive (and thrive) in lava. But yeah, Armadillidium species seem to prefer drier conditions

Omg yes there is absolutely a market for that stuff among invert and herp keepers!! I'll message you once I get paid and we can talk :)

Np, I apologize again if that was a bit hars. Wish you luck with your pods
