Structural and physical determinants of the proboscis–sucking pump complex in the evolution of fluid-feeding insects

Abstract Fluid-feeding insects have evolved a unique strategy to distribute the labor between a liquid-acquisition device (proboscis) and a sucking pump. We theoretically examined physical constraints associated with coupling of the proboscis and sucking pump into a united functional organ. Classifi...
