Insect
Salpingogaster nigra
Salpingogaster nigraSalpingogaster nigra is a slender, wasp-mimicking hoverfly native to the Neotropics, widely recognized as a beneficial natural predator in agricultural ecosystems. Adult females seek out frothy spittle masses on grasses, laying eggs directly alongside sap-sucking nymphs. The voracious maggot larvae burrow straight into the protective foam to consume destructive pasture and sugarcane froghoppers before transforming into pupae.
