The pharaoh ant (Monomorium pharaonis) is a small (2 mm) yellow or light brown, almost transparent ant notorious for being a major indoor nuisance pest, especially in hospitals. [1] A cryptogenic species , it has now been introduced to virtually every area of the world, including Europe , the Americas, Australasia and Southeast Asia .
The little black ant (Monomorium minimum) is a species of ant native to North America. [1] It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with ...
Tapinoma sessile is a species of small ant that goes by the common names odorous house ant, sugar ant, stink ant, and coconut ant. [1] Their colonies are polydomous (consisting of multiple nests) and polygynous (containing multiple reproducing queens ).
Queen offspring ants among most species develop from larvae specially fed in order to become sexually mature. Depending on the species, there can be either a single mother queen, or potentially hundreds of fertile queens. [2] Not every colony of ants has a queen. Some colonies have multiple queens. Queen ants are the only members of a colony to ...
Since ants of this species are so small, they can colonize just about anywhere. They can live in people's homes without them ever knowing that they have an infestation of tiny ants. Solenopsis molesta are common in homes, and due to their small size they can easily enter sealed packages of food. Other thief ant colonies are inside other ant ...
Leptanilla japonica is an uncommon [1] highly migratory, subterranean ant found in Japan. [2] They are tiny insects, with workers measuring about 1.2 mm and queens reaching to about 1.8 mm, and live in very small colonies of only a few hundred individuals at a time [2] (as compared to the 60,000 to 20,000,000 individuals of legionary ant colonies. [3])
Workers can range from 3.5 to 7.5 mm (0.14 to 0.30 in) in length. [1] The queen ant's size can range from 4 to 10 millimetres (0.16 to 0.39 in). [2] This species can be distinguished from other subgenus by little amounts of erect hairs on the gena, limited erect hairs on the clypeal disc and finally by the color which is a concolorous dark brown-black.
The species is a common pest in the United States, particularly in the states of Hawaii and Florida, although the species is expanding further north, even reaching Texas by the mid 1990s. [11] They are commonly found in the southern parts of Florida, and is considered a key pest, along with several other invasive ant species. [12]
