Like other insects, ants perceive smells with their long, thin, and mobile antennae.

Like most insects, ants have compound eyes made from numerous tiny lenses attached together.

In some parts of the world (mainly Africa and South America), large ants, especially army ants, are used as surgical sutures.

Before striking, the ant opens its mandibles extremely widely and locks them in this position by an internal mechanism.

In South Africa, ants are used to help harvest rooibos ( Aspalathus linearis ), which are small seeds used to make a herbal tea.

Some of the ants classified as pests include the pavement ant, yellow crazy ant, sugar ants, the Pharaoh ant, carpenter ants, Argentine ant, odorous house ants, red imported fire ant, and European fire ant.

And in harvester ants, I divide the tasks of the ants I see just outside the nest into these four categories where an ant is foraging, when it's out along the foraging trail, searching for food or bringing food back.

In biology, scout bees and ants will return home to tell the others where food is to be found, the fact of fertility must be announced to prospective mates from the same species, and the presence of danger must be passed as a warning to others in the group.
