The Queen is born in a similar way to the Soldier alien, but her incubation period is longer - several days instead of several hours. Her cranium is much larger and flatter and she is approximately two to three feet taller than the Soldier. She also has four arms instead of two. The Queen, similar to a queen ant, is the only reproductive female in the hive and directs its operation - from its construction to the location of suitable hosts. It is believed that she communicates her will through the secretion of pheromones or possibly by an empathic link. She is also more intelligent than the Soldiers and Drones.
