Ants and scale insects are often tight ecological associates, even under the soil. Here, a first instar ground pearl (Eurhizococcus brasiliensis) is carried by a Linepithema micans worker. The ground pearls produce honeydew that feeds the ants, while the ants protect the pearls and carry their young to new host plants.
