I checked on my two colonies today. I found larvae in both colonies! I'm very excited. I might just make it.
As for getting the colonies to take up residence in a more suitable test tube set up, I might just need to call the sheriff to evict them. Man these are stubborn ants. Their cotton Is drying up a bit, and they certainly seem ready to move, but just won't do it. I might just try taping the new set up together with the old.
An interesting observation. One colony appears to have tired of the whole feeding larvae thing, so they just placed them on top of a meal worm I left for them, to eat their fill. Lazy, lazy ants.
