So earlier this week, I happened to get super lucky and bumped into a wandering queen ant. I suspect she’s of the Camponotus genus, due to being of such large size. She’s already laid a few eggs and has been guarding them ferociously.
But it’s hard to say whether she is fertilized or not. Although she shed her wings already, it is not guaranteed that she is fertilized. It is possible she was unable to mate and simply gave up.
The only way we will know is when the eggs hatch: whether they are winged males or wingless workers.
