The waist can be made up of one or two small segments, depending on the species. Ants are social insects living in colonies comprised of one or a few queens, and many workers. The queen generally stays deep and safe within a nest. Most ants that you see are workers and these are all females. Depending on species, workers may be similar in size, or come in a range of sizes.
Ants tend to come in dark or earth tones.
Different species are black, earth-tone reds, pale tans, and basic browns. Ants are very diverse and it is difficult to generalize about them. When ant colonies reproduce, the new queens and males may be found in the colony. Males generally have small heads, large eyes, large thoraces, and a pair of claspers at the end of the gaster. After mating, new queens break off their wings and never fly again.
