Fire ant
Fire ants were a highly successful Earth insect that tended to inhabit countries with warmer climates. These ants could be found throughout the southern regions of North America, much of South America, and Australia. They tended to be red in color and had a sting which was extremely painful to Humans.

Ensign Harry Kim described having the Akritirian clamp synaptic stimulator as being akin to having "a million fire ants in my brain," after he and  Tom Paris were each fitted with one in 2373. Zio, believing they sounded vicious, suggested Kim use his visualization to enable him to resist the clamp, picturing waves of such ants as comprising an army that could defeat the clamp. ()
