How do larvae sustain the entire adult population during feeding?

Answer

By converting hard-to-digest animal protein into easily absorbed energy

The relationship hinges on the larvae acting as efficient, living food processing units. The adult workers bring back complex, hard-to-digest animal protein in the form of chewed insect matter. The larvae possess the specialized digestive capabilities to break down this raw protein slurry into its core components. In exchange for receiving this necessary building material, the larvae process it and secrete a highly refined, easily digestible, sugary liquid. This nutrient-rich liquid is then consumed by the adult workers, ensuring that the high-protein diet consumed by the young ultimately fuels the entire adult population tending to them.
