Yellow crazy ant

The yellow crazy ant (Anoplolepis gracilipes) is a species of ant, introduced accidentally to northernAustralia and Christmas Island in the Indian Ocean, that has caused ecological damage in both locations and now found in the northern suburbs of Brisbane. It is colloquially called "crazy" because of its erratic movements when disturbed. Its long legs and antennaemake it one of the largest invasive ant species in the world.

The yellow crazy ant’s natural habitat is not known, but it has been speculated that the species originated in West Africa. It has been introduced into a wide range of tropical and subtropical environments including Caribbean islands, some Indian Ocean islands (Seychelles,Madagascar, Mauritius, Réunion, the Cocos Islands and the Christmas Islands) and some Pacific islands (New Caledonia, Hawaii, French Polynesia, Okinawa, Vanuatu,Micronesia and the Galapagos archipelago). The species has been known to occupy agricultural systems such as cinnamon, citrus, coffee and coconut plantations. Because the ant has generalized nesting habits, they are able to disperse via trucks, boats and other forms of human transport.
