Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 are extant and four subfamilies are extinct , described from fossils .
Strumigenys minutula is a species of ant found in Japan and Taiwan. [1] This is the smallest ant in its genus (workers less than 2 millimetres (0.079 in) in length) and can be easily identified by size alone, as well as by characteristically short, strongly curved mandibles. [1]
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 ).
[135] [136] Some species of ant are able to use the Earth's magnetic field for navigation. [137] The compound eyes of ants have specialised cells that detect polarised light from the Sun, which is used to determine direction. [138] [139] These polarization detectors are sensitive in the ultraviolet region of the light spectrum. [140]
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.
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 ...
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 ...
The adult males are winged, and the Queen ants are 5mm long. [6] The workers are Monomorphic, meaning that the worker ants do not vary in shape, size or function. [7] A worker ant has a length of 2–3 mm and is typically brown in colour. [8]
