Belonging to the Anoplolepis gracilipes Family. These are small, dark gray to black ants that are easily recognized by their extremely long legs and antennae. Crazy ants get their name from their habit of running about very erratically with no apparent sense of direction. Colonies most often can be found living in soil, under items such as logs, stones, landscape timbers, wood, debris and above-ground swimming pools. Crazy ants feed on a wide variety of foods, including other insects, grease and sweets. They have been known to feed on the larvae of fleas and flies, and also have been observed carrying away fire ant queens immediately after a swarm.
