Many myrmecophiles eat waste in ant nests, such as dead ants or fungi growing in the nest. Some myrmecophiles make food that the ants can eat. Aphids do this when they make honeydew. Ants may even farm or tend some insects, such as aphids, that make food for them. Other myrmecophiles eat the food supplies of ants, and a few eat ant eggs, larvae, or pupae.
