Queen

Queens, which are fertile females, look much the same as the workers, except they are about twice their size. They also have a sting. |

The males (called drones) have long antennae which often curve backwards. Their gaster has seven visible segments and is more evenly-shaped and longer than that of the females, and they have no sting. |
