Ant biology
Ants are insects: six legs, two elbowed antennae and a body in three parts, the head, the thorax (mesosoma) and the abdomen (gaster), joined by a narrow waist.
A colony works as one unit. The queen lays the eggs. Workers, all female, care for brood, dig, forage and defend. Winged males and new queens appear only when a colony is mature enough to reproduce.
Ants talk mostly through chemicals called pheromones, which students can see at work when workers follow a trail to food.
