Hey, just curious about your Myrmoteras bingahmii colony. Do they sometimes also just throw out random cocoons in your outworld and just leave it there? My colony had 3 cocoons and 2 of them were thrown out and eaten by the springtails and dwarf isopods (they usually eat decaying stuff, that's why I assume that the cocoons are dead). I keep them in a tropical terrarium in a test tube which has high humidity and warmer temperature.
Hope that you can still answer my questions because it's pretty concerning to me. There is very little information about these little ants on the internet .
And of course, Good luck on your exams!
