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. It is a ...
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 ).
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 ...
Established by French zoologist Pierre André Latreille in 1809, the subfamily has more than 3,000 described species, placing it as the second largest ant subfamily. Despite this, the hyperdiverse genus Camponotus is the most diverse group of ants in the world, with more than 1,100 species described. [41] [110]
In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to raise new queens in the colony. [94] Some ants produce sounds by stridulation, using the gaster segments and their mandibles. Sounds may be used to communicate with colony members or with other species. [95] [96]
At least two species are invasive in other parts of the world. B. chinensis, the most studied Brachyponera species, has been introduced as an exotic ant in southeastern United States and New Zealand. The other invasive species, B. sennaarensis, is spreading through the Middle East. [2]
The longhorn crazy ant is able to invade new habitats and outcompete other species of ants. In 1991, in the large closed dome of the research station Biosphere 2 in the Arizona Desert, no particular ant species was dominant. By 1996, the longhorn crazy ant had virtually replaced all the other ant species.
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.
