Since larvae dont need the moisture, and the maculata rearing attempt was done in an open plastic bag, I imagine that a well-ventilated aquarium with screen lid would be enough for larvae. The lid is to prevent adults from flying off.
Since McMonigle,s Ult. Guide states that fungus darklings need low ventilation and high humidity (this is certainly false for maculata larvae, but maybe not adults), give the adults a choice between their dry fungus, some damp hiding areas in the aquarium, and some dry hiding areas. This way they can self-regulate humidity, and if the fungus is far away from the damp areas it will probably stay dry and not moldy. It seems that ventilation is unimportant as long as humidity is present; my Diaperis rufipes? were semi-diurnal and could be seen walking around in the open at day and night. They seemed to be primarily nocturnal, however.
Good luck on finding a colony!
Ladybug darkling is a very good English name, if you ever need to make one up for the shop.
Random note: Aah, all the quotation marks, apostrophes, and some commas have vanished mysteriously, and refuse to appear when typed! Danged technology, sometimes. I may have to tell Peter about this.
