What diet fuels the rapid growth of wasp larvae underground?

Answer

High-protein diet

The developing wasp larvae, which exist as grub-like stages housed within the paper nest cells, require a diet extremely rich in protein. This high-protein intake is an absolute necessity because it serves as the essential building block material needed to fuel their extremely rapid growth rate and successfully undergo the complex process of metamorphosis into fully formed adult wasps. Without this concentrated source of animal matter procured by the worker adults, the larvae cannot develop the necessary tissues and musculature to survive and mature. Sugary liquids alone are insufficient for their structural development.
