The eggs will eventually turn into larvae. These are similar to maggots. However, they have no eyes or major organs and are limited to wiggling and opening their mouths. The queen or worker ants will help feed them. They are covered in tiny hairs that stick to each other, this enables the queen or workers to pick up many at once.
Most larvae grow into worker ants. However, in developed colonies, larvae fed with more food may grow up to become virgin winged queen ants.
