Yellow Crazy Ant

Recognizable by its extraordinarily long legs and antennae, yellow-brown coloration, and absence of a sting, relying instead on spraying formic acid to subdue prey.

Pantropical distribution; native to Southeast Asia and Indian Ocean islands, but now a high-profile invasive species across Pacific islands, Australia, and parts of the Americas.

Polygynous and capable of forming massive, interconnected supercolonies. They exhibit exceptionally rapid population growth and high aggression towards other species.

Requires large setups with escape-proof barriers. Provide a continuous supply of sugars and proteins, while ensuring high humidity and excellent ventilation to disperse trapped formic acid.

Explosive population growth makes long-term containment difficult; in confined or poorly ventilated nests, their own sprayed acid can be deadly to the colony.

Their acid spraying has devastated native wildlife on Christmas Island, severely reducing the iconic red crab population and altering the local ecosystem.
