      Big-headed ant intercepted at Charleston port

      Officials at the Port of Charleston have intercepted a dangerous intruder.

      CHARLESTON, S.C. (AP) -- Officials at the Port of Charleston have intercepted a dangerous intruder.

      The Post and Courier of Charleston reported that customs officials say they found what is known as the big-headed ant and other insects in a container of aluminum scrap metal on a ship from Costa Rica.

      Steve Switzer with the customs office in Charleston says the ant eats native plants and other insects. It has been known to eat irrigation pipes, telephone cables and electrical wires.

      Switzer says the big-headed ant can lead to species extinctions.

      Customs and Border Patrol agriculture specialists sent more than 10 insect specimens from the ship to a U.S. Department of Agriculture entomologist. One of the insects was identified last week as the "big-headed ant."
