A new invasive pest ant was discovered near Pasadena, Texas in 2002 by Tom Rasberry, a pest management professional.  This ant was called the Rasberry crazy ant after its discoverer.  It is also called the Tawny crazy ant (official common name), hairy crazy ant, and Caribbean crazy ant.  The scientific name is Nylanderia fulva.   Crazy ants get their name because they crawl around like crazy.
