I have recently received two more Odontomachus bauri queens from Brazil to restart / continue my research journal on these ants. I noticed that once again, the queens have begun to build unique half-moon founding chambers as seen in the photos. One of the queens have begun to lay eggs and currently has one egg. The other queen is yet to lay. I noted that these queens require a higher level of moisture in order to create their founding chambers which suggests that they probably found their colonies in the wild in a muddy environment.
The queens currently feed exclusively on a homemade mixture:
1 part dry organic cricket powder
1 part water
2 parts honey
1 part sugar
Heat for about 45 seconds and stir, then allow to cool to room temperature before use. One small droplet should be sufficient for approximately 2-3 days. Clean after 2 days.
Anyways, until more updates, cheers!
