Ground pearls are the large, sedentary adult forms of root-sap feeding insects. Here, two Eurhizococcus brasiliensis hang suspended from grape roots deep underground while a Linepithema micans ant gathers the honeydew exuded by the pearls. These insects are significant pests in Brazilian vineyards.
