I moved Cherub's paddling pool and discovered the ants had built a nest underneath. There were hundreds (or thousands!) of eggs - by the time I thought to get the camera the ants had already hidden a good proportion of them.
Here are some ants busily carrying eggs down a hole in the bottom left corner of the picture.
Cuter and more furry than the ants were our little visitors from playgroup, who were playing hard to get in their tunnel on the one occasion I remembered the camera.
