Fire ants of those species invasive in the United States can be distinguished from other ants locally present by their copper brown head and thorax with a darker abdomen. The worker ants are blackish to reddish and their size varies from . In an established nest these different sizes of ants are all present at the same time.

for biting.

Behavior

A typical fire ant colony produces large mounds in open areas, and feeds mostly on young plants, insects and seeds. Fire ants often attack small animals such as small lizards and can kill them. Unlike many other ants, which bite and then spray acid on the wound, fire ants bite only to get a grip and then sting (from the abdomen) and inject a toxic

Fire ants are more aggressive than most native species, so have pushed many species away from their local habitat. One such species that ''Solenopsis'' ants parasitically take advantage of are bees, such as '' Euglossa imperialis'', a nonsocial orchid bee species, from which the ants enter the cells from below the nest and rob the cell's contents. These ants are renowned for their ability to survive extreme conditions. They do not hibernate, but can survive cold conditions, although this is costly to fire ant populations as observed during several winters in Tennessee, where 80 to 90% of colonies died due to several consecutive days of extremely low temperatures. Fire ants have been known to form mutualistic relationships with several species of

in 2017, clumps of fire ants, known as rafts, were seen clumped together on the surface of the water. Each clump had as many as 100,000 individual ants, which formed a temporary structure until finding a new permanent home. Ants so clumped, recognize different fluid flow conditions and adapt their behavior accordingly to preserve the raft's stability. Fire ants dig tunnels efficiently using about 30% of the population of the colony, thereby avoiding congestion in tunnels.

Queens, males and workers

Queen

Fire ant queens, the reproductive females in their colony, also are generally the largest. Their primary function is reproduction. Typically, a fire ant queen will seek to establish a new colony following a nuptial flight, wherein it will use its special venom to paralyze offending competitors, in the absence of workers for defense. Fire ant queens may live up to seven years and can produce up to 1,600 eggs per day, and colonies will have as many as 250,000 workers. The estimated potential life span is around 5 years and 10 months to 6 years and 9 months. Young, virgin fire ant queens have wings (as do male fire ants), but they often cut them off after mating. Although, occasionally a queen will keep its wings after mating and through her first year.

Males (drones)

Male fire ants mate with queens during a nuptial flight. After a male has successfully inseminated a queen, he will not get accepted back to the mother colony, and will eventually die outside the nest.

Workers

The other roles in an ant colony are usually undertaken by workers. Fire ant workers are haphazardly divided into different size classes, namely minima, minor, media, and major workers. The major ants are known for their larger size and more powerful mandibles typically used in macerating and storing food items (i.e. as repletes), while smaller workers take care of regular tasks (the main tasks in a colony are caring for the eggs/larvae/pupae, cleaning the nest, and foraging for food).
