Combining insect sampling and household surveys, our research found significant economic benefits arising from ladybird beetles (for insect geeks, there are three main species: Harmonia axyridis, Propylea japonica, and Coccinella septempunctata). We’ve calculated that each adult bug provides services worth $0.01 per year, even alongside substantial insecticide use.
