Workers, queens and drones
Most of the wasps in a nest are infertile female workers.
|Short antennae||Sting||Six segments visible on gaster|
|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.|
