Ghost ants, which get their nickname from their transparent abdomen, are among the tiniest of ants. Native members of the species feed on honeydew and cattle aphids, tiny sap-sucking insects. They share this sweet tooth with the bee hummingbird, the smallest known bird. By batting its wings up to 200 times per second, it is able to sample the sweet nectar of up to 1500 flowers per day.
