The state of Arizona is home to a variety of black ants. There are 318 native species of ants in Arizona, more than in any other state in the U.S., according to AntWeb. Arizona is home to so many species due to its location at the confluence of many biotic regions.
Despite the name, this variety of ant is often actually black in color, according to AZ Ants. The worker fire ants are either black or red in color. Fire ants are so named because of their reputation for being able to inflict a great deal of pain through stings and bites. Worker fire ants are different sizes, with some being 1/4-inch long and others being only 1/16-inch long. Many fire ants are ground-nesting ants.
Black ants are generally active day and night, spending a great deal of time foraging for food. The size of a black ant is varied. The little black ant measures only about 1/16 inch, while other black ants exceed 1/2 inch. A worker black ant spend its whole life finding and delivering food back to the nest.
Carpenter ants are black and hollow out galleries in wood for their nesting needs, according to AZ Ants. This nesting habit is known to cause structural damage to buildings. Worker carpenter ants as well as queens grow to be quite large, with worker ants getting up to 1/2 inch in length and queens growing up to 5/8 inch. Colonies of carpenter ants are moderate in their size.
Harvester ants are found in urban areas. Their nests get to be quite large, with about 12,000 worker ants. These nests are found in open areas near sources of food. Harvester ants are either black or reddish-brown. Harvester ants are known to cause a lot of damage to crops as they gather vegetation and seeds, according to AZ Ants. In mating season, males and females often have wings as they look for a new nesting site.
