The ants that make this type of colony use the large bulb-like chamber to grow fungus which they feed on. They literally farm the fungus, collecting bug feces and other debris to use as fertilizer. The structure is definitely one of the most unique that I have seen so far. The single entrance tunnel actually splits into three separate tunnels just before connecting to the main chamber, making it resemble a kidney or some sort of organ. A single tunnel extends down from the main chamber and ends abruptly. Other casts of this species I have done have multiple chambers deeper in the ground.
Base Description
I made this cast early on in this project and only recently came up with a good way to mount it. The base is a custom cut oak board. I also rounded the corners with a router and stained it. There are two round pegs at the top and bottom which the tunnels are inserted into for stability. There is also a ¼" bolt securing the main chamber to the display board. The board has a fixture on the back so it can hang on the wall.
