Without wings, they can generally be distinguished from workers by their larger body size, larger thorax and larger abdomen. All workers are females. Ant larvae are white and grub like. They have no legs and don't move about much on their own. You can generally see a large, dark stomach through their cuticle.
Ant pupae look like white adult ants, with their legs and antennae pressed close to their bodies.
In some species, larvae spin silk and the pupal stage is inside a cocoon. Newly emerged adult ants are often paler than older ones. It may take them several days to reach their final color. Food Most ants that are easy to keep in the classroom are generalists, eating a variety of small insects that they capture, dead insects they happen to find, nectar, or honey dew. They need a balance of carbohydrates and protein.
