POGONOMYRMEX BADIUS

A plaster cast of a large Pogonomyrmex badius -the Florida harvester ant - 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 (Research Department of Biological Scienc - Florida State University Walter R.
