body of an ant is clearly divided into three sections: the
head, the thorax, and the gaster. (The narrow waist is actually
within the abdomen, so the part of the abdomen behind the
waist is called the gaster.) 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.
