Coronatus, maybe?

I believe this Acromyrmex is in fact coronatus. She is beautiful and doing well, although I cannot see any pupae yet.

Rose petals

The Acromyrmex are doing fine. All 7 queens have fungus, and three queens already have workers. It is great to watch them go about their business. It is almost time to give them more space. They absolutely love rose petals and leaves.
