I caught a Myrmica sp. queen over the summer. She laid a clutch of about ten or so eggs very soon after capture. Despite frequent feedings, her brood developed slowly, as well as some being cannibalized. Now, roughly three months after capture, she has her first pupae, and it's a worker pupae, meaning she is fertile. I had had my doubts due to how slowly her brood developed. She now has one pupae, one large larvae, one small larvae, and one egg.
