"WEST LAFAYETTE, Indiana -- An ant species common to the mainland United States that is known for its tropical smell has invaded Hawaii for the first time. A population of odorous house ants, Tapinoma sessile, has been found at an upland site on the island of Maui. Also called stink ant, and coconut ant, these ants got their names because they invade houses and smell like coconut when smashed."

"Purdue University entomologist Grzegorz Buczkowski says the Maui invasion is the first confirmed record for this species outside its native North American range.

"Odorous house ants in Hawaii are not like they are here in natural areas where they live in small colonies. They are creating megacolonies like they do in urban areas," said Buczkowski, whose findings were published in the journal "Myrmecological News." "
