As soon as the pupae were exposed, the tiny worker ants, whose job it is to look after the nest and keep it tidy, would scuttle around collecting the pupae in their jaws. They would then take them to safety below ground.
I was keen to capture this behaviour but had to be quick because the ants barely paused for a second. Their tiny size (2-3mm in length) only added to the difficulty. The 2 images below are probably the best that I managed.
