Here’s a shot of a hidden world. This plaster cast is of the INSIDE of a Florida Harvester Ant’s nest. It has 135 chambers and 12 meters of vertical shafts. Quite an architecture.
I liked this quote, which gives such a societal feeling to the colony. Basically they’re saying the young ants work at the deeper end, while the old ants stay near the surface:
“Carbon dioxide concentrations increased 5-fold between the surface and the depths of the nest. A preference of young workers for high carbon dioxide concentrations, and a tendency for workers to dig more under low carbon dioxide concentrations could explain both the vertical age-distribution of workers, and the top-heaviness of the nest’s architecture.”
“A plaster cast of a large Pogonomyrmex badius nest. This nest consisted of 135 chambers and 12 meters of vertical shafts. The top-heavy distribution of chamber area and spacing is typical for the species, as are the helical shafts and the decrease of chamber size with depth (photo by Charles Badland).”
