The yellow crazy ant is considered an invasive species of catastrophic potential, having been introduced to its new range of habitats accidentally. Moreover, due the large size of both its antennae and legs, early 21st century experts consider it the largest invasive ant species on the planet. These ants are sometimes referred to as "tramp ants," due to their ability to cross vast distances atop pieces of driftwood or even in ships, thus allowing for their extensive migratory range.

Yellow crazy ants are considered scavengers, feeding on everything from scale insects to tree sap. The ants secrete a sweet-sticky substance called honeydew onto the trees, causing mold to grow over leaves and stems. In some island locations, yellow crazy ants are known to develop supercolonies, which constitute extreme threats to local ecological balances. For example, on Johnson Atoll, one supercolony alone possessed approximately 1,000 queens and covered nearly a quarter of the entire island.
