Our bit of 'lawn' in front of the house is peppered with ants nests, mostly red meadow ants. First mow of the year and I carelessly removed the top of one yesterday and disturbed a nest of ants, black, small, no idea what type. The reaction from the ants was incredible. Frenzy of activity, hundreds of ants running to and fro, pulling and pushing the dozens of exposed eggs, trying to get them back underground. How they communicate I can't imagine but they all looked like they knew what to do. Within minutes they'd mostly moved the eggs and within half an hour, apart from the exposed soil, you wouldn't have known they's been there. Nature truly is remarkable.
