Here's my new Polyrhachis cfr. dives colony, started from a single queen caught in november in Khao Yai, Thailand. Small colony and still in a test tube, opened a few days ago in a small arena. The ants quickly closed the entrance of the test tube with silk.

Now there are about 25 workers and the same number of big larvae and pupae.
I cannot see anymore inside the test tube, which has been covered with silk.
