Neat setup! I have a few ants myself including a mystery (to me) camponotus spp. which is at a similar stage (two workers, 3 pupae, 5-10 larvae, ? amount of eggs. I also have several species that I take care of in the lab (I'm a grad student currently working with ants). What are you feeding them? Are the workers foraging yet? The workers of the species of camponotus that I have are strictly nocturnal so I never see them forage, but I see evidence that they have.
