Correction to: Nature Communications https://doi.org/10.1038/s41467-023-36376-5, published online 28 February 2023The original version of this Article contained an error in Equation (2) for fluidic pumping, and incorrectly read: \({\eta }_{{{{\rm{ex}}}}}=\frac{\rho {u}^{2}}{2}+\frac{32\mu lu}{{d}^{2}}+\frac{4\gamma }{d}\). The correct form of Equation (2) is: \({\eta }_{{{{\rm{ex}}}}}=\frac{32\mu lu}{{d}^{2}}+\frac{4\gamma }{d}\).

AbstractFood consumption and waste elimination are vital functions for living systems. Although how feeding impacts animal form and function has been studied for more than a century since Darwin, how its obligate partner, excretion, controls and constrains animal behavior, size, and energetics remains largely unexplored. Here we study millimeter-scale sharpshooter insects (Cicadellidae) that feed exclusively on a plant’s xylem sap, a nutrient-deficit source (95% water).
