Many of the larvae are now pupae. Some smaller larvae are now seen. Some of the pupae have eclosed, maybe about 8 or so.
A dozen workers are usually in the outworld at any given time, foraging, attempting to drain my waterers, or plotting escape plans.
Dean, sorry, but despite watching I have yet to see the queen fed. But they are not bringing anything obvious into the nest like sand and she is not leaving the nest.
I think they are chewing very small bits off of the mealworms and crickets and offering the morsels to the larvae. But I have been unable to tell for certain since I don't have time right now to sit in front of them and observe for more than 10min or so.
They do not like regular room lighting, but if it is a bit dimmer they are fine. I have a piece of paper standing vertically between the nest and the light bulb in the room.
They have taken their old game to new heights. They now play a daily round of "Let's see if we can pile up a 5cm band of sand and empty the waterers before she gets home from work again!"
It got to the point where they could drain my normal waterers in 6 hours. Despite trying the usual tricks like putting them on a rock or on top of an empty waterer, they quickly caught on and adapted their draining strategy.
For quite some time the ByFormica Mercury feeder had them confused, but then they caught on and can pile up enough sand to empty it in 12 hours or less. Adding 1cm of cotton beneath the feeder gave me another week of breathing room while they tried to figure out how to pile sand on the cotton properly.
Today I set the feeder inside of a lid that belonged to a larger feeder so even if they do drain it, it won't soak into the grout/sand outworld floor. I have some other good ideas, but they need more than the 4" of head room that their current outworld allows.
Eventually, they will run out of sand that they can pull off of the outworld floor. Then I assume they will pile any garbage possible such as meal leftovers.
Within a year or so, I am going to need a larger (and completely escape proof) outworld to keep up my tricks to keep the waterers undrainable. As it is, I am very glad that the lid has a secure seal and that the air holes are covered in steel mesh. How these ladies are walking over fluon without care I have no idea. The flightless fruit flies fall right back down.
