Читать полностью…Worker ants, which are assigned the role of "storage", are called plerergates.
They place the extracted food in the blind process of their esophagus (goiter). As the goiter increases, all the internal organs of the ant move away. The abdomen of the "storage" ant can increase 4-5 times and reach 6-12 mm in diameter.
In winter, when hunting and prey are reduced, the ant colony "uncovers honey barrels". To do this, the worker ants send special signals to the plerergates with their antennae. After receiving the signal, the "keeper" shares food with his relatives by trophallaxis.
