Ceraunus blue caterpillars
These ants aren't trying to eat the caterpillar; they're trying to protect it! In a phenomenon called myrmecophily, ants and lycaenid caterpillars, such as the Ceraunus blue caterpillar (pictured), team up for survival. The ants protect the caterpillars, and the caterpillars secrete a nutritious substance called honeydew. Interestingly, the ants will touch the caterpillars with their antennae to get them to produce the honeydew.
